摘　　要：依据结合部相互接触表层结构形式,提出一种基于虚拟材料的固定结合面建模方法,根据结合面的大小和结合部相互接触表层厚度来设定虚拟材料长宽及厚度,利用结合面元单元接触刚度矩阵与虚拟材料的实体单元刚度矩阵之间的等效原则获得虚拟材料的特性参数,实现了利用结合面元法建模所获得的结合面实验数据的工程应用,并借助实例验证了该方法的可行性。Based on the structural form of mutual contact layer of joint interfaces, a method of modeling of fixed joints based on virtual materials was proposed, According to the size of joint interfaces and the thickness of mutual contact layer of joint interfaces, the width and thickness of virtual material was set up, and the characteristic parameters of virtual materials was obtained by principle of equivalence between the contact stiffness matrix of joints unit, the entity unit matrix of virtual materials, the engineer application of experimental data obtained by the joints unit method of modeling was realized, and the practical examples are given to verify the feasibility of this method.
