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

Rock masses are heterogeneous materials containing a large number of discontinuities, and
the failure of the natural rock mass is induced by the crack propagation and coalescence of …

The maximum tensile stress criterion and the Mohr-Coulomb criterion are incorporated into
the extended non-ordinary state-based peridynamics (NOSB-PD) to simulate the initiation …

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 …

In this paper, we propose a simple 2D and 3D crack evolution algorithm which avoids the
variable/DOF map** within mesh adaptation algorithms. To this end, a new area/volume …

Abstract The Cracking Elements Method (CEM) is a numerical tool for simulation of quasi-
brittle fracture. It neither needs remeshing, nor nodal enrichment, or a complicated crack …

We propose a simple and efficient algorithm for FEM‐based computational fracture of plates
and shells with both brittle and ductile materials on the basis of edge rotation and load …

We propose an alternative, simpler algorithm for FEM-based computational fracture in brittle,
quasi-brittle and ductile materials based on edge rotations. Rotation axes are the crack front …

Realistic 3D finite strain analysis and crack propagation with tetrahedral meshes require
mesh refinement/division. In this work, we use edges to drive the division process. Mesh …

In the context of plane fracture problems, we introduce an algorithm based on our previously
proposed rotation of edges but now including the injection of continuum softening elements …
