A CORRECTED COHESIVE ZONE MODEL IN THE INTERLAMINAR FRACTURE OF COMPOSITE

open access: yesJixie qiangdu, 2021
In order to consider both material damage of the crack tip and the initial fracture toughness,a corrected cohesive zone model( CZM) that considers the influence of material damage of the initial crack propagation has been proposed. The corrected cohesive

Numerical aspects of phase field models for low-temperature fracture in asphalt mixtures

open access: yesCase Studies in Construction Materials, 2023
Unlike the cohesive interface element model, the phase field model (PFM) is a newly developed computational model which provides a unified approach to predicting crack nucleation, propagation, coalescence and branching without any ad-hoc criterion.
