摘要
本文在无厚度节理单元的基础上，建立了等厚度的节理单元，并导出了相应的刚度矩阵。根据材料的本构关系，对节理单元进行了非线性分析，给出了对称形式的弹塑性矩阵。
According to Goodman joint element, the equal thickness joint element has been developed.From stress-strain relations, the author discusses the nonlinear problems. The stiffness matrix and elastic-plasticmatrix are presented.
