The ballasless track has been massively applied nowadays, while the interface damage
evolution of ballastless tracks is still rarely investigated. This work aims to investigate the …

Damage tolerance assessment is a keen topic in modern industrial product design. Under
certain loading conditions fatigue crack growth is elastoplastic and the Paris' law becomes …

In the past decade, the cohesive zone model has been receiving increasing attention as a
powerful tool for the simulation of fatigue crack growth. When applying cohesive zone model …

Cyclic cohesive zone models represent powerful numerical tools to describe and predict
different phenomena of fatigue. In the present paper a review is given about the state of the …

A modified cyclic cohesive zone model (CCZM) is developed for low-cycle fatigue crack
initiation prediction for subsea pipelines. The traction and separation law in the model is …

基于ABAQUS 有限元软件建立内聚单元模型以研究I 型弹塑性疲劳裂纹的扩展过程. 利用UEL
子程序定义内聚单元的疲劳损伤累积准则以识别疲劳裂纹扩展过程中裂纹尖端的位置 …

Most cohesive zone models were used to reproduce fatigue crack growth under small scale
yielding and failed to predict elastic–plastic fatigue crack growth. In the present work a new …

This study presents incremental finite element computations of creep‐fatigue crack growth in
Alloy 718 at 65 0° C in air. Alloy 718 is representative of creep‐brittle materials, in which …

Fatigue crack growth is analyzed for steady state and overload conditions. The model
combines an elastic-plastic strain gradient hardening material and an irreversible cohesive …

An irreversible cohesive zone model was used to understand how plastic strain gradients
and yield strength mismatches affect fatigue crack growth across bi-material and multilayer …
