Parametric studies on SEA parameters for coupled plates made of composite laminate Sridhar N Shastry, Subrahmanya S Swamy Journal of Vibroengineering, 2022 Statistical Energy Analysis (SEA) has been used to compute velocity responses and Coupling Loss Factors (CLF) for two composite laminates joined in a 'L' junction configuration. Two case studies were carried on SEA. The effect of fibre orientation on SEA parameters was studied. The effects of internal damping were also determined. The computation of SEA parameters has been done using classical wave approach and Finite Element Method using Nastran/Patran. CLF determined using classical wave approach is independent of fibre orientation and internal damping factor. This study using FEM reveals that the SEA parameters vary in comparison with classical wave approach as fibre orientation and internal damping are also considered in the analysis. Also, by classical wave approach, the CLF varied linearly with the increase in frequency while there was some scatter in CLF determined by finite element method.
Study on High Frequency Vibrations using Statistical Energy Analysis for Different Composite Materials Sridhar N Shastry, S Subrahmanya Swamy Iop Conference Series Materials Science and Engineering, 2020 Statistical Energy Analysis developed in early 1960s is used to determine the vibration response and energy levels in the structures subjected to high frequency vibrations by using statistical approach. In this work, Statistical Energy Analysis parameters like coupling loss factor and velocity response for composite plate like structures are analytically determined. Velocity response and coupling loss factor for L-shaped composite plate like structure subjected to point load have been computed for three different composite materials. Velocity response and coupling loss factors were determined and compared for the materials considered. The results show that composite materials having high specific modulus had low velocities and high coupling loss factor.
