IMPROVEMENT OF THE NUMERICAL PREDICTION OF DUCTILE FAILURE WITH AN INTEGRAL NO...
F. X. C. Andrade; Pires, F. M. A.; de Sá, J. M. A. C.; Malcher L.In this contribution, the implementation of a nonlocal formulation is described aiming to improve the reliability of the numerical prediction of ductile failure. The nonlocal model, which is based on a simplified version of Lemaitre's material model [1], is achieved by redefining the damage variable to be nonlocal using an integral formulation. The nonlocal constitutive problem is then discretised with respect ...
