摘要

The focus is on isotropic damaging materials where damage is driven by the nonlocal equivalent strain. The nonlocal equivalent strain definition is inserted into the work function by a Lagrangian multiplier. This Lagrangian formulation depends on: displacement, nonlocal equivalent strain and Lagrangian multiplier, and provides a variational basis supporting multifield formulations of both integral and implicit gradient type. Finite element results are presented for some representative one- and two-dimensional examples.
