Abstract
In this contribution, a length-dependent model for describing problems characterized by the presence of a fracture process zone (FPZ) of finite width is presented. A FPZ generally develops in structural elements made of elasto-damaging or quasi-brittle bulk in front of a crack/notch tip [1]. The current formulation grounds on the REgularized XFEM framework proposed for cohesive interfaces in [2], herafter called REXFEM.File in questo prodotto:
