不同受力状态下木材本构模型研究进展
Research progress on the constitutive models of timber under different stress states
摘要
Abstract
There are significant difficulties in the calculation efficiency and convergence of numerical simulation of timber structures,when complex constitutive models of timber were adopted to describe the mechanical behavior of timber under different stress states.Based on the existing research progress on the constitutive models of timber,the yield criterions,hardening laws,flow rules and damage rules were clarified,and the advantages and disadvantages of these rules were compared.Different constitutive models of timber were assessed to provide suitable constitutive models of timber for the numerical simulations of timber,timber members and timber joints.Reasonable and efficient constitutive models of timber under different stress states were summarized,aiming to provide reference for the future researches on the constitutive models of timber and the numerical simulation of timber structures.关键词
