This paper presents a modified regularized formulation of the Ambrosio–Tortorelli type to
introduce the crack non-interpenetration condition in the variational approach to fracture …

Failure of quasi-brittle materials is governed by crack formation and propagation which can
be characterized by two phases:(i) diffuse material degradation process with initial crack …

Both experiments and theoretical investigations have evidenced the existence of
compressive-shear fracture mode in geomaterials like concrete, rocks and gypsum. Proper …

This article presents a continuous–discontinuous approach that provides a discontinuous
character to the quasi-brittle fracture process, modeled in a continuous setting through a …

This paper presents a thorough analysis of potential-based and non-potential-based
cohesive zone models (CZMs) under conditions of mixed-mode separation and mixed-mode …

Three regularization concepts are assessed regarding their variational structure and
interference with the predicted physics of (quasi-) brittle damage: the fracture energy …

A new continuous‐discontinuous strategy for the computational modeling of crack
propagation within the context of phase‐field models of fracture is presented. The method is …

This paper proposes a novel technique to reduce the computational burden associated with
the simulation of localized failure. The proposed methodology affords the simulation of …

In this work, two fracture modelling methods ie, extended FEM (XFEM) and localizing
gradient damage method (LGDM), are combined to get the advantages of both methods …

Apart from major cracks and delamination, extensive and diffused short matrix micro-cracks
are generally observed in composite laminates. In principle, discrete crack models (DCM) …
