A thermodynamically consistent nonlocal formulation for damaging materials

摘要

A thermodynamically consistent nonlocal formulation for damaging materials is presented. The second principle of thermodynamics is enforced in a nonlocal form over the volume where the dissipative mechanism takes place. The nonlocal forces thermodynamically conjugated are obtained consistently from the free energy. The paper indeed extends to elastic damaging materials a formulation originally proposed by Polizzotto et al. For nonlocal plasticity. Constitutive and computational aspects of the model are discussed.
