The relative equation between stressintensityfactor and displacement field near interface crack tip of bimaterials was derived firstly.
首先推导了双材料界面裂纹尖端的位移场和应力强度因子之间的关系式。
2
The transient displacement field and the dynamic stressintensityfactor at the moving crack tip are obtained.
给出了瞬态的位移场和运动裂纹尖端的动态应力强度因子。
