结合异种材料界面自由边附近的应力可以用一个常规应力项和一个或两个应力奇异项的和来描述。提出了一种由有限元结果计算相应应力强度因子的方法，可用于同时确定两个应力强度因子。对某些几何形状的结果表明，这三项对热应力界面自由边缘附近的应力分布有显著影响。
Stresses near the free edges of the interface of bonded dissimilar materials can be described by the sum of a regular stress term and one or two stress singularity terms. A method for the calculation of the corresponding stress intensity factors from finite element results is presented which is useful to determine two stress intensity factors together. Results for some geometries show that all three terms may contribute significantly to the stress distribution near the free edge of the interface for thermal stress.
