Abstract
A numerical strategy for modelling both diffuse and localized cracking in elastodamaging continua is proposed. The approach is based on the REgularized eXtended Finite Element Method (REXFEM), which has been presented in [1] [2] for assigned interfaces of elastic and cohesive type. Here, the crack development and propagation and the determination of the discontinuity path within the strain localization band are considered. The potential of the approach is that a regularization length is introduced, which can be both larger and smaller than the representative size of the finite element, while all variables remain local. © CIMNE.File in questo prodotto:
