Strong embedded discontinuities for simulating fracture in quasi-brittle materials [PDF]

open access: yes, 2011
In this paper embedded strong discontinuities are used to model discrete cracking in materials like concrete. In the approach followed a discontinuous displacement field is considered and the deformation is localized at a surface of zero width.

Investigation of Mixed-Mode I/II Fracture under Impact Loading Using Split-Hopkinson Pressure Bar

open access: yesApplied Sciences, 2020
Mixed-mode fracture of construction building materials under impact loading is quite common in civil engineering. The investigation of mixed-mode crack propagation behavior is an essential work for fundamental research and engineering application.

Fracture resistance dataset of composites under mixed-mode non-proportional loading

open access: yesData in Brief, 2021
Cohesive zone modelling is one of the main tools to simulate fracture of materials and structures. As a result a number of cohesive laws are being developed continuously.

Mixed mode I/II/III fracture assessment of PMMA using a new test fixture [PDF]

open access: yesMATEC Web of Conferences, 2019
Brittle and quasi-brittle fracture has been recognized as the main failure mechanism in various structural components. Due to complexity of the components’ geometry and loading condition, a combination of tensile, in-plane shear and out of plane shear ...

A thermodynamically consistent derivation of a frictional-damage cohesive-zone model with different mode i and mode II fracture energies [PDF]

open access: yes, 2015
The present paper deals with the derivation of an interface model characterized by macroscopic fracture energies which are different in modes I and II, the macroscopic fracture energy being the total energy dissipated per unit of fracture area.
