An energy-based differentiable finite element framework for elastic and path-dependent elastoplastic solids

This paper proposes a finite-element-integrated deep energy method (DEM), hereafter referred to as FE-integrated DEM, for linear elasticity and path-dependent J 2 /von Mises plasticity. The method targets a central difficulty in neural elastoplastic solvers: path-dependent internal variables must be evolved consistentl...
