基于横观各向同性假定的固定结合部本构关系及有限元模型
A Constitutive Law Based on Transverse Isotropic Hypothesis and Finite Element Model of Fixed Joints
摘要
Abstract
A finite element method modeling fixed j oints was presented.In the method,the conG tact layers of the fixed j oints were regarded as a homogenous virtual transverse isotropic material.AcG cording to the relations among deformations and loads of j oints,the nonlinear relations among 5 indeG pendent variables and normal stress in constitutive matrix were deduced,and then the relations were introduced into finite element analysis to model fixed j oints.The analytical results and experimental results of the j oints were compared and the validity of the method was confirmed.关键词
