| 摘 要： | 本文采用非局部弹性理论。用Love位移函数导出三维轴对称问题的非局部弹性应力的一般形式解,并求解了圆盘裂纹问题。得到了裂纹尖端区的应力是有界的,再次证实了非局部理论模型求解断裂力学问题的正确性。

| Abstract: | This article is concerned with the penny-shaped crack in an infinite body subjectecd to a uniform pressure on the surface of the carck in nonlocal elasticity. Making use of Love function in classical elasticity,we reduce the stress solution of an axisymmetric problem of the penny-shaped crack. The result of this article shows the stress on the crack tip is finite and demonstrates again the correctness of the nonlocal model for solving problems in fracture mechanics. |
