The importance of the cohesive-zone approach to analyse localisation and fracture in
engineering materials is emphasised and ways to incorporate the cohesive-zone …

In this paper, we present a self-propagating Strong Discontinuity embedded Approach
(SDA) for quasi-brittle fracture. The method is based on the Statically Optimal Symmetric …

The dissipated strain energy, representing a monotonically increasing state variable in
nonlinear fracture mechanics, can be used to develop an arc-length constraint equation for …

The cracking elements (CE) method is a recently presented self-propagating strong
discontinuity embedded approach with the statically optimal symmetric (SDA-SOS) …

A comparative study on finite elements for capturing strong discontinuities by means of
elemental (E-FEM) or nodal enrichments (X-FEM) is presented. Based on the same …

The paper focuses the numerical modelling of material failure in a strong discontinuity
setting using a continuum format. Displacement discontinuities, like fractures, cracks, slip …

Gradient theories, as a regularized continuum mechanics approach, have found wide
applications for modeling strain localization failure process. This paper presents a second …

Some new aspects of the continuum strong discontinuity approach (CSDA) to model
material failure in geomaterials are addressed. A new global algorithm, for tracking multiple …

A simple methodology to model shear bands as strong displacement discontinuities in an
adaptive meshfree method is presented. The shear band is represented by a displacement …

Robustness and stability of the Continuum Strong Discontinuity Approach (CSDA) to
material failure are addressed. After identification of lack of symmetry of the finite element …
