| 摘 要： | 均质各向同性弹性含裂纹固体在外载荷作用下裂纹尖端场表现出奇异性。由两种弹性材料组成的界面裂纹结构,除表现出奇异性外,随着向裂纹尖端靠近,裂纹前方出现应力振荡特性和裂纹表面的相对位移相互嵌入现象。本文从破坏力学的角度对有关问题进行了分析讨论,并给出了适当力学模型的有限元法算例。

| Abstract: | The crack-tip field of the homogen-isotropic elasic solid material having crack under load behaves singularity, but for the interface crack constructure of the material consisted by two elastic materials, as the crack goes forwad to the crack point, stress vibration and relative movoment of the crack surface will inset each other, this paper, from the angle of fracture mechanics, analyses some relevant problems and presents some definite-element examples. |
