纤维增强复合材料多模式内聚断裂的相场模型
Phase-field model for multi-pattern cohesive fracture in fiber reinforced composite material
摘要
Abstract
The classical fracture phase-field model is a variational method based on brittle fracture theory,which cannot accurately characterize the quasi-brittle fracture behavior of composite material.Based on this,a multi-phase-field model was proposed to describe the multi-pattern cohesive fracture behavior of fiber reinforced composites material.A hybrid cohesive fracture phase-field model was proposed by reasonably defining the phase-field driving force and the damage constitutive relationship for the anisotropic material,and the corresponding evolution equation and strength criterion were derived.The model was used to simulate the crack propagation and failure of three kinds of composite plates.The results showed that the proposed multi-phase-field model could effectively simulate the multi-pattern cohesive fracture behavior of composite material,and had high application value.关键词
