Continuum modelling of stress diffusion interactions in an elastoplastic medium in the presence of geometric discontinuity
Rupesh Kumar Mahendran, Hirshikesh, Ratna Kumar Annabattula +1
Chemo-mechanical coupled systems have been a subject of interest for many decades now. Previous attempts to solve such models have mainly focused on elastic materials without takin…

Modified Stoney's equation with anisotropic substrates undergoing large deformations
Sai Sharan Injeti, Nihit Vyas, Ratna Kumar Annabattula
Residual stresses in a thin film deposited on a substrate results in a curvature of the system, which can be measured using the well known Stoney equation. Isotropic elasticity of…
