求翻译：求解（2）式应力应变关系的具体表达式，有两种方法：一种方法是找出[D]矩阵后，再找出与残余应力对应的弹性矩阵、应变，并进一步将残余应力对应的弹性矩阵和应变等效到弹性矩阵与应变项之中，这样可以得到一个与无残余应力情况下应力应变关系形式相同的表达式。另一种方法是在找出[D]矩阵后，直接获得与应力项对应的残余应力，从而得到应力应变关系。是什么意思？

Solving (2) stress-strain relationship of concrete expression, in two ways: One method is to find the [d] matrix, and then find out the corresponding elastic and residual stress matrix, strain, and the corresponding residual stress elastic matrix and the strain is equivalent to the elastic matrix an

(2) the stress-strain-specific expression of the relationship, there are two ways: one way is to identify [D ] matrix, and then find the corresponding with residual stress resilient matrix, contingency, and further flexibility for residual stress response equivalent to Matrix and matrix and continge

Solves (2) type the stress-strain relations the concrete expression, some two methods: After one method is discovers the (D) matrix, then discovers with the residual stress correspondence elastic matrix, the strain, and further the residual stress correspondence elastic matrix and the strain equival

Solution (2) type stress strain relationship of specific expression type, has two species method: a method is find [d] matrix Hou, then find and residual stress corresponds to of elastic matrix, and strain, and further will residual stress corresponds to of elastic matrix and strain equivalent to el
