The present study deals with the fabrication of hybrid composites using biodegradable and ecologically friendly natural fibers and a recyclable thermoplastic matrix. Pure and hybrid natural fiber composites of high-density polyethylene (HDPE) with Kenaf and Ramie fiber, 20 wt%, were fabricated using microwave-assisted compression molding. The composite's mechanical characterization was performed using tensile, flexural, impact, and hardness tests. X-ray diffraction was done to investigate the crystallinity percentage, and scanning electron microscopy of fractured surfaces was performed to determine failure mechanisms. The hybrid composite of HDPE/Ramie and Kenaf exhibited the highest ultimate tensile strength (UTS) at 29.3 ± 1.2 MPa, surpassing HDPE/Kenaf (21.6 ± 1.1 MPa) and HDPE/Ramie (24.3 ± 1.4 MPa) composites. In terms of flexural strength, HDPE/Ramie demonstrated the highest at 19.9 ± 1.5 MPa, while HDPE/Kenaf had the lowest at 18 ± 1.1 MPa. The hybrid composite's flexural strength was intermediate at 19 ± 1.3 MPa. Impact strength followed a similar trend, with the hybrid composite leading at 40.2 KJ/m2, followed by HDPE/Ramie (26.9 KJ/m2) and HDPE/Kenaf (12.3 KJ/m2). Hardness tests revealed the highest hardness in the hybrid composite and the lowest in HDPE/Kenaf. A computational study has been performed to develop a model for predicting the hybrid composites. A strong agreement between both studies has been observed. The developed composite is deemed suitable for various light-duty applications, such as roofing, car interior panels, and mobile covers, offering potential benefits in reducing carbon footprint.

In this paper, a comprehensive investigation of the design and analysis of Ti-6Al-4V hip joint implants using generative design and topology optimization, along with laser powder bed fusion (LPBF), an additive manufacturing technique, has been presented. The study employed the NSGA-II genetic algorithm for generative design, enabling the generation of diverse optimized designs and topology optimization with the solid isotropic material penalization approach, efficiently reducing implant mass of the design space by up to 75% while maintaining structural integrity. Finite element analysis revealed comparable von Mises stress and deformation levels between geometries obtained with generative design and topology optimization. However, the combined approach exhibited superior performance, namely, topology optimization followed by generative design, with a 40% reduction in deformation and a 15% reduction in von Mises stress compared to conventional models. LPBF simulations demonstrated the superiority of the optimized geometries, with a 30% reduction in thermal stress and a 66% reduction in deformation compared to conventional designs. It is observed that design input for generative design significantly impacts the output design. Also, geometry has a notable impact on the quality of the printed part.

Urban Air Mobility (UAM) has gained traction in the aviation industry. With the ever-increasing rate of urbanization, congested roads have become a common phenomenon in megacities across the world. Urban Air Mobility in the form of Electric Vertical Take-off and Landing (eVTOL) aircrafts presents an opportunity to revolutionize the transportation sector by providing sustainable intercity and intracity travel for the urban dwellers. Amongst the different eVTOL configurations, the tilt-rotor and hybrid lift + cruise configuration aim to combine the advantages of fixed wing and rotary wing aircrafts. The presented work aims to develop a detailed design procedure for the propellers of a tilt-rotor eVTOL aircraft to maintain low noise emission and to have high efficiency to utilize the capacity of current battery technology to the maximum extent. Multiple configurations such as coaxial tilt-rotor and hybrid lift + cruise were considered for the aircraft, and preliminary design calculations were carried out for all of these configurations to decide the number of rotors, diameter of the rotor, number of blades and the power required for take-off, hover and cruise performance of the aircraft. These calculations were performed based on the concepts of actuator disc theory/momentum theory. A propulsion configuration was selected based on the results of the above-said calculations provides such as tip Mach number, efficiency and rotor diameter to facilitate low noise and compactness. After selecting the configuration, the propeller blades were designed based on blade element theory. Since tilt-rotors are used for both hover and cruise conditions, it becomes necessary to analyze them for both conditions. Since the operating conditions such as airspeed and rpm are very different in hover and cruise conditions, the tilt-rotors were designed as controllable-pitch propellers to ensure all the sections of the blade operate at the desired angle of attack for both hover and cruise conditions. Computational Fluid Dynamics (CFD) simulations were carried out for the same to verify the results. The outcome of the current work is the theoretical dimensions and geometry of the propellers which provide the required thrust, efficiency and low noise emission for the considered eVTOL aircraft.

Abstract Multistable laminates have attracted the attention of researchers for developing morphing structures, as they can stay in different stable configurations without any need for external forces to maintain any of those configurations. In this study, a novel application of a reconfigurable antenna made with rectangular composite laminates [90/0] in the shape of a star is analyzed using the Variational Asymptotic Method (VAM), which is free of ad-hoc assumptions and highly accurate, unlike semi-analytical theories present in the literature. The star shaped laminate is modeled as a plate using geometrically exact kinematics, and thermal analysis is done by applying uniform temperature to obtain its cool-down shape, which shows multistability. Snap-through forces are applied on the structure to change to the other stable configurations. Three parametric studies are performed to identify the variation of snap-through force. These studies are carried out by varying the aspect ratio, curing temperature, and thickness of the individual rectangular laminates to identify the lower and upper limits beyond which the laminate loses its multistability. All studies performed using VAM are validated against 3D FEA in ABAQUS are found to be in good agreement with each other although, VAM handled the 3D problem at the 2D level achieved by systematic dimensional reduction. The computational efficiency is found to increase by almost 70% compared to 3D FEA.

Linear vibratory feeder is one of the most extensively used part feeding systems in a production line. The part motion on the feeder can be sliding or hopping or a combination of these two. Based on the dynamics of part motion this paper identifies three distinct regimes. A mathematical model was developed that can predict the trend in conveying velocity in these regimes. This model can provide the parts position as a function of time and has considered relative displacement between the part and the conveying surface. The simulation was validated by performing experiments for a range of vibration frequencies and amplitudes.

In this work, a three-dimensional thermomechanical finite element model has been developed to simulate the additive manufacturing process of a Ti-6Al-4V hip implant fabricated using the laser powder bed fusion process. The developed numerical model is used to predict the thermal fields, residual stresses, and part deformation during the printing process. To reduce the mass and consequently the weight of the hip implant, topology optimization has been carried out. Furthermore, the additively manufactured Ti-6Al-4V hip implant subjected to realistic loading conditions is analyzed. In the numerical model, new elements are activated for each layer to simulate the recoating of metal powder, and the thermal gradient, residual stress, and deformation associated with the layer are computed. It is observed that the implant geometry significantly influences the quality of the printed part. Topology-optimized geometry shows a notable reduction in residual stress generation and distortions, along with a significant reduction in mass.

The motion of a part on a curved surface mounted upon a linear vibratory feeder is of great importance in mass production. In this article, the conveying surface or track is modelled by a bilinear surface inclined to all axes with the curvature varying throughout the surface. An experimental test rig is fabricated to study the part motion on the feeder surface. Dynamics of the part on the surface is derived and the path traced by the part is obtained numerically. The numeric model closely correlates with experimental results. Based on the control parameters two distinct regimes—slide and hop—are presented, highlighting their relation to frequency and amplitude of vibration of the feeder.

The current work talks about a stochastic approach to study the static response characteristics of natural fiber reinforced composites with random material and geometric properties. Stochasticity in macro scale is due to randomness in macro mechanical properties of bio composite which is inevitable owing to many uncontrollable parameters in manufacturing and fabrication processes of bio composites. Analysis is also done by taking ply orientation angles (meso scale) and other geometric properties like aspect ratio, thickness ratio as discrete random variables. Bio composite is made of sisal fiber(Natural fiber) and matrix based on Epoxidized Soybean-Oil(ESO). Macro-mechanical analysis of composite laminates is done using Finite element analysis and first order shear deformation theory (FSDT) is used for displacement formulation. Results are shown for different boundary conditions along with different stacking sequences and thickness ratios. Uncertainty quantification is done using Monte Carlo simulation technique by considering the mean and the standard deviation of input material properties of the bio composite to be known. Sensitivity analysis is done to show how each stochastic input parameter (Elastic modulii) influence thecomposite plate response characteristics. The validation of the modelis checked using the existing results which are in agreement with the results obtained. Results indicate that stochasticity in material or geometric properties of bio composite cannot be ignored. It is concluded that considering stochasticity of input parameters in design and analysis of structures is crucial to maintain structural integrity, safety and reliability.
