英语翻译
In the finite element method,the stiffness matrix is often obtained from the strain energy.According to the previous section,the non-zero stresses in the adhesive are the shear stresses τzx and τzy .Thus,the strain energy Va in the adhesive can be written as(公式省略).
In this work,a quadrilateral element is adopted and the shape functions are as follows（公式省略）.
Within the quadrilateral element,the shear stresses can be expressed as（公式省略）.
where (τzx)i and (τzy)i are the shear stresses at the ith node.Using equation (12) for the shear stress in the adhesive,(τzx)i and (τzy)i can be written as（公式省略）.

答案

在有限单元法中,刚度矩阵经常获得应变能量.根据以前的部分,零应力在胶黏剂中是tzx和tzy的剪切应力.因此,应变能量Va在胶黏剂中能被写成XXX.在这次作业中,一个四边形元素被采用并且形状函数是以下的XX在四边形元素里,...
