摘要
采用完全非线性弹性理论，研究了两类不可压缩材料形成的界面裂纹尖端场．通过将裂纹尖端场划分为收缩角区和扩张角区，得到并求解了裂尖场的渐近方程，揭示了应力、应变场所示的奇异特性．
The elastostatic field near the interface crack tip between two incompressible materials is analyzed with the fully nonlinear theory. By dividing the crack tip field into shrinking and expanding regions, the asymptotic equations for the crack tip field are derived and solved. The singularities of stress and strain near the crack tip are revealed.
