A CORRECTED COHESIVE ZONE MODEL IN THE INTERLAMINAR FRACTURE OF COMPOSITE
Jixie 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

MODELLING OF CRACK PROPAGATION: COMPARISON OF DISCRETE LATTICE SYSTEM AND COHESIVE ZONE MODEL
Acta Polytechnica CTU Proceedings, 2020 Lattice models are often used to analyze materials with discrete micro-structures mainly due to their ability to accurately reflect behaviour of individual fibres or struts and capture macroscopic phenomena such as crack initiation, propagation, or ...
