Level set-based topology optimization of micropolar solids under thermo-mechanical loading
Mayank Shekhar, Ayyappan Unnikrishna Pillai, Subhayan De +1
We propose a novel level set-based topology optimization for micropolar solids subjected to thermo-mechanical loading. To capture the size effects, we have incorporated the microst…
Alpha-VI DeepONet: A prior-robust variational Bayesian approach for enhancing DeepONets with uncertainty quantification
Soban Nasir Lone, Subhayan De, Rajdip Nayek
We introduce a novel deep operator network (DeepONet) framework that incorporates generalised variational inference (GVI) using Rényi's -divergence to learn complex operators…
Model Falsification for Predicting Dynamical Responses of Uncertain Structural Systems
Subhayan De, Tianhao Yu, Patrick T. Brewick +2
Accurate prediction of dynamical response of structural system depends on the correct modeling of that system. However, modeling becomes increasingly challenging when there are man…
Likelihood Level Adapted Estimation of Marginal Likelihood for Bayesian Model Selection
Subhayan De, Reza Farzad, Patrick T. Brewick +2
In computational mechanics, multiple models are often present to describe a physical system. While Bayesian model selection is a helpful tool to compare these models using measurem…
