英语翻译
Having the stiffness matrix for the adhesive as shown in equation (19),we can couple the stiffness matrix of the adhesive to the stiffness matrices of the composite patch and damaged laminate.According to Jones and Callinan [9],the interlaminar shear stresses τzx and τzy in the patch and laminate can be neglected with only a few percent error.In this investigation,the stiffness matrices of the composite patch and damaged laminate are derived based on the standard plane stress formulation.Using the standard finite element assembly procedure,we can incorporate the stiffness matrix of the adhesive along with the stiffness matrices of the composite patch and damaged laminate,thus producing the system stiffness matrix for the adhesively
bonded composite laminate.

有了方程（19）所示的胶粘剂刚度矩阵,我们就可以将胶粘剂的刚度矩阵与复合材料补片和损坏的层压材料的刚度矩阵结合起来.根据琼斯和卡里南的（理论或计算等）[9],层间剪切应力τZX和补片与层压材料的τZY可以忽略不计,其误差只有百分之几.本次科研中,在标准平面应力公式的基础上推导出了复合材料补片和损坏的层压材料的刚度矩阵.通过使用标准的有限元装配程序,我们可以将胶粘剂的刚度矩阵与复合材料补片和损伤层压板的刚度矩阵合并,从而产生粘结复合材料的系统刚度矩阵.
