界面裂纹的 Cell-Based 光滑有限元法研究
Research on Cell-Based Smoothed Finite Element Method of Interface Cracks
摘要
Abstract
To improve the accuracy of the fracture parameters of interface fracture structure ,based on the interfacial fracture mechanics and smoothed finite element method ,Cell‐Based smoothed finite element method was proposed to solve the fracture parameters of bi‐material interface crack ,and the smoothing cells of the interaction integral method was given to obtain the stress intensity factor .The central interface cracks of bi‐material infinite plate were simulated ,and the FEM calculation results and the analytical solu‐tion were compared .The relationships among the number of elements ,the number of subdomain and nor‐malization stress intensity factors as well as the convergence of the proposed method were discussed .Nu‐merical example results show that this method has good convergence and high accuracy and can be designed and manufactured as necessary references for researchers and engineers in multilayer materials .关键词
