Rigorous characterization of fracture evolution in quasi-brittle materials–such as concrete–
requires computationally intensive and, mostly, complex approaches. However, the …

This paper presents a novel and robust three-dimensional plain concrete cracking model
applicable to the study of structural stability of large structures, such as dams, while …

Modeling complex material failure with competing mechanisms is a difficult task that often
leads to mathematical and numerical challenges. This work contributes to the study of …

This study employs the numerical analysis and experimental testing to analyze the fracturing
mechanics and the size of rock cones formed in the pull-out of a system of three undercut …

The continuum strong discontinuity approach (CSDA) is suitable for the analysis of material
failures of quasi-brittle solids when constitutive damage models are applied to kinematic …

A three-dimensional numerical method considering the boundary effect on fracture energy
and initial fracture toughness was proposed to simulate the whole propagation process of …

Fatigue simulation requires accurate modeling of unloading and reloading. However,
classical ductile damage models treat deformations after complete failure as irrecoverable …

This article presents a novel two-dimensional quadrilateral solid finite element model,
enhanced by incompatible modes and embedded strong discontinuity for simulation of …

Damage and failure in quasi-brittle materials such as rocks, concrete, and ceramics, have a
complex non-linear behavior due to their heterogeneous character and the development of …

According to the theory of linear elasticity, the conventional numerical methods are difficult to
calculate the singular stress fields of three dimensional V-notched/cracked structures …
