On characterization of cohesive zone model (CZM) based upon digital image correlation (DIC) method [PDF]

open access: yesInternational Journal of Mechanical Sciences, 2022
Abstract Cohesive zone model (CZM) has been extensively applied in numerical simulation of interfacial fracture behaviors such as composite delamination and fracture of adhesive joints. Accurate and efficient identification of CZM parameters signifies an important research topic to enable reliable analysis and design of these structures.

A peridynamics-based cohesive zone model (PD-CZM) for predicting cohesive crack propagation

International Journal of Mechanical Sciences, 2020
Abstract Since Dr. Silling proposed the peridynamics (PD) theory, PD has been successfully utilized to predict brittle crack propagation problems, however, a precise PD model with the prediction ability for quasi-brittle failure is still lacking.

Phase-field regularized cohesive zone model (CZM) and size effect of concrete

Engineering Fracture Mechanics, 2018
Abstract A phase-field regularized cohesive zone model (CZM) was recently proposed for both brittle fracture and cohesive failure within the framework of the unified phase-field damage theory. Motivated from the fact that this model gives length scale and mesh independent global responses for problems with or without elastic singularities, we further

Failure analysis of thin-walled composite profiles subjected to axial compression using progressive failure analysis (PFA) and cohesive zone model (CZM)

Composite Structures, 2021
Abstract In the presented paper, the phenomenon of failure of axially compressed thin-walled composite structures with channel shape was analysed. The tested thin-walled structures were made of CFRP composite using the autoclave method. In the research, experimental tests on actual columns and advanced numerical calculations using the finite element ...
