SOUKAT KUMAR DAS

Dr Soukat Kumar Das joined NIT Rourkela in June 2023 as a faculty member in the Dept of Civil Engg. He has more than 8 years of research experience in the field of granular mechanics, Discrete Element Method (DEM), ground improvement techniques, Machine Learning and constitutive modelling of geomaterials. His current research area includes understanding the potential of carbon sequestration in the Indian peninsula and developing closed-loop geothermal systems. Before joining NIT Rourkela, he worked as a postdoc at King Abdullah University of Science and Technology (KAUST, KSA) where he worked on understanding the effect of drill string vibrations on wellbore stabilities. He completed his PhD from IIT Kanpur in 2021, and the major focus of his doctoral work was to decipher the effect of crushing on the rate-dependent response of granular media. He got his Masters from IIT Roorkee in 2015. His Under graduation is from Jadavpur University in Civil Engg (2013).

The conventional methods for determining the shear strength parameters of soil, namely cohesion (C) and angle of internal friction (φ), involve time-consuming and expensive machinery. Also, the extraction metal ore processing into metal and machine manufacturing involves a high level of carbon emission. During the operation of these machines a large quantity of electricity is generated in thermal power plants, leading to an indirect increase in the carbon footprint, thus suggesting a need for the adoption of more sustainable practices. This study is aimed at reducing net zero emission by laboratory testing machines by develop a predictive machine-learning model for estimating soil shear strength parameters by utilizing the existing soil data. An artificial neural network (ANN) is one such model inspired by the human brain, with the ability to learn complex patterns and relationships in data. For this, 88 soil samples in all were gathered from the literature that was available. Basic index properties of soil are used as inputs and C, φ are predicted as outputs. A neural network is developed using a Bayesian regularization optimization algorithm. The model developed is evaluated using the root mean squared error, coefficient of determination, and mean absolute error. The efficacy demonstrated by the ANN model ensures reliable predictions, thus promoting the adoption of these predictive models, leading to net zero carbon emissions in the testing field of geotechnical engineering.

Strain rate-dependent undrained response of a coral sand

Geotechnique Letters, 2024
The strain rate-dependent response of sand is influenced by particle crushing. However, such a conclusion is drawn in the previous studies, primarily based on drained triaxial or 1D compression tests on crushable sand. This study explores the interplay of strain rate and crushing behaviour of sand under undrained triaxial (CU) conditions. We perform CU tests on coral sand under different confining pressures and relative densities. Two different axial strain rates in the quasi-static range are used to explore the rate-sensitive response of coral sand. The undrained experiments reveal that a slow strain rate and high confining pressure lead to higher crushing, as commonly observed in drained triaxial experiments since dilatancy diminishes. However, CU tests on dense samples also demonstrate higher crushing than medium dense samples, which is a counterintuitive observation. Later, it is analysed that crushing evolution before and after phase transformation and corresponding pore pressure generation plays a pivotal role in the undrained response. In addition, strain rate also governs the particle crushing and peak strength of the sand samples. This study proposes a generalized rate-dependent breakage index that satisfactorily predicts the correlation between relative breakage and plastic work under different rates, relative densities, and confining pressures.
