基于VCCT、CZM和XFEM的复合材料Ⅰ型分层扩展数值模拟方法研究
Numerical Simulation Method for Mode Ⅰ Delamination Growth of Composite Materials Based on VCCT,CZM and XFEM
摘要
Abstract
Establishing a numerical simulation method for delamination growth in composite materials and mastering its characteristics is of great significance for predicting the residual strength of composite structures,which can provide technical support for the design and analysis of damage tolerance in composite structures.Virtual crack closure technology,cohesive zone model,and extended finite element method are three common numerical methods.However,there is a lack of in-depth comparative research on the characteristics of these three methods in modeling the delamination of composite laminates,which greatly confuses the use of numerical methods.This paper takes mode I delamination as the research object,establishes two-dimensional and three-dimensional finite element models using three methods,comprehensively compares the three simulation methods,and finally analyzes the advantages and limitations of each method.The research results can provide theoretical support for the application of numerical methods for delamination simulation.关键词
