A mean-field homogenisation scheme with CZM-based interfaces describing progressive inclusions debonding [PDF]

, 2019
The objective of the present study is to describe the progressive debonding of inclusions in particle or fibre reinforced composites. To do so, the mean-field homogenisation scheme of Mori-Tanaka is enriched to take into account imperfect interfaces. The

Crack onset analysis of adhesives for the CZM-VCCT method

, 2017
For testing and analysing crack propagation under fatigue loading, crack onset precedes any crack growth. In this work, crack onset during the testing of Double Cantilever Beam (DCB) specimens is studied.

diffcohesive: an open-source differentiable cohesive-zone finite element package for fracture simulation and interface-law identification

SoftwareX
Ready-to-use open-source software for cohesive-zone modelling (CZM) of interfacial fracture is scarce, and setting up cohesive elements, mixed-mode laws, and path-following solvers from scratch requires considerable iteration.
