摘 要:
利用J积分得到了一般条件下双材料界面裂纹的能量释放率（SERR），并按照裂纹尖端法向应力为0和Ⅰ和Ⅱ型耦合量JⅠ．Ⅱ为0的条件得到了应变能量释放率的Ⅰ型和Ⅱ型分量．其应变能量释放率分解的结果表明，轴力和弯矩都会产生Ⅰ型和Ⅱ型应变能量释放率分量．[著者文摘]

Abstract:
The strain energy release rate （SERR） of bimaterial interface fracture was calculated under general condition by use of J-integral. The mode Ⅰ and mode Ⅱ of SERR were obtained under the condition that both the normal stress at the tip of cracks and the coupling J Ⅰ ,Ⅱ between mode Ⅰ and mode Ⅱ were zero. The result of decomposition of SERR shows that both the axial force and the bending moment can produce mode Ⅰ and mode Ⅱ of SERR.[著者文摘]
