【摘要】 本文采用完全非线性弹性理论,研究了橡皮类材料在Ⅰ型荷载作用下的平面应力裂纹问题,指出,裂尖变形由两个收缩区和一个扩张区组成,裂尖应力场具有R^-2nδ的奇异性.更多还原

【Abstract】 Based on the fully nolinear theory of elasticity, the crack tip field in a rubber-like thin sheet under model-I loading condition is studied.We point out that the deformation near the crack tip is composed of two narrowing regions and one expanding region, and the stress has the singularity R--2nb.更多还原
