摘要
建立一种混凝土材料损伤模型 ,并将该模型应用于混凝土材料的损伤分析 ;以连续损伤力学理论为基础 ,应用J .Lamaitre的“应变等效性”假说 ,和“利帕托夫强度”理论作为破坏准则 ,对混凝土材料的Pfeiffer和Bazant试件在直剪和压剪载荷作用下的损伤发展过程进行了数值模拟 ;与S .E .Swartz和N .M .Taha实验结果作了比较 ,二者较吻合 ;
To establish an isotropic damage model for the analysis of concrete; Based on the theory of damage mechanics continum and “strain equivalence”hypothesis proposed by Lamaitre and using “Hasomhof strength” theory as destroy criterion, damage developing process for Pfeiffer and Bazant specimens of concrete materials is modeled numerically by this model; To accord well with the experimental results by S.E.Swartz and N. M.TaHa;This model is proved to be feasible in the damage analysis of concrete.
