In this work, a critical comparison between three different numerical approaches for the
computational modelling of quasi-brittle structural failure is presented. Among the many …

One major merit of phase-field models for fracture is that cracks nucleation, propagation,
branching, merging, coalescence and even fragmentation, etc., can be accounted for …

Aiming to bridge the gap between damage and fracture mechanics for modeling localized
failure in solids, this paper addresses a novel geometrically regularized gradient-damage …

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 …

In this work, we propose a novel weighting for the interfacial consistency terms arising in a
Nitsche variational form. We demonstrate through numerical analysis and extensive …

The optimal design, reliable manufacture and durable utilization of electromechanical
systems demand objective modeling of failure under coupled electric field and mechanical …

This work addressesnumerical comparison between the extended finite element method
(XFEM) and the phase-field regularized cohesive zone model (PF-CZM)(Wu, 2017, 2018a) …

This paper introduces a new algorithm to define a stable Lagrange multiplier space to
impose stiff interface conditions within the context of the extended finite element method. In …

Owing to the solution space enriched with a priori known knowledge through the partition of
unity, the extended or generalized finite element method (XFEM/GFEM) has been widely …

Composites or multi-phase materials are characterized by a distinct heterogeneous
microstructure. The failure modes of these materials are governed by several …
