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 …

Concrete is the most widely used man-made composite material. Its damage and fracture
behavior determines reliability of many engineering structures. The quasi-static fracture …

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 …

This paper presents the results of a numerical FEM analysis of the effect of embedment
depth on the extent of the failure zone (cone failure) under the effect of an undercut anchor …

The paper presents the results of a numerical analysis using the Finite Element Method
(FEM) of the friction issue in the contact between the undercut anchor head and rock during …

The importance of crack propagation in the structural behaviour of concrete and masonry
structures has led to the development of a wide range of finite element methods for crack …

The geometrical description and tracking of non-planar crack surface with curved crack front
evolving in 3D are a big challenge for crack modeling. We develop a numerical method for …

This work exploits the high accuracy of the mixed 3− field u/e/p formulation to address
materially non-linear inelastic problems including isochoric deformations. Motivated by the …

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 …

The testing of mode III and mixed mode failure is every so often encountered in the
dedicated literature of mechanical characterization of brittle and quasi-brittle materials. In …
