英文摘要: Abstract(#br)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 not applicable. In the past decades numerous cohesive zone models were proposed and investigated for predicting elastoplastic fatigue crack growth. However, three-dimensional cracks were not considered properly. The constraint effects to cohesive zone modeling were not explicitly studied so that the three-dimensional crack cannot be analyzed reasonably. Different cyclic cohesive zone models were introduced but lacking in experimental verifications. In the present paper cohesive zone models for three-dimensional crack growth under both monotonic and cyclic loading conditions are critically reviewed...
