摘要

给出了计算无限各向异性弹性板共线裂纹应力强度因子的权函数。裂缝的数量和长度都是任意的。权函数适用于裂纹面荷载，可能是非自平衡荷载。结果表明，对于自平衡荷载，权函数与弹性常数无关。然而，对于非自平衡载荷，出现了一个与材料相关的附加常数项。

Weight functions for an array of collinear cracks in an infinite anisotropic elastic plate

Weight functions are provided for calculating the stress intensity factors for collinear cracks in an infinite anisotropic elastic plate. The number of cracks as well as the length of the cracks are arbitrary. The weight functions are for crack-face loading, which may be non-self-equilibrium. It is shown that for self-equilibrium loading, the weight functions are independent of elastic constants. For non-self-equilibrium loading, however, an additional constant term that is material-dependent appears.

期刊介绍： The objective of the Journal of Mechanics is to provide an international forum to foster exchange of ideas among mechanics communities in different parts of world. The Journal of Mechanics publishes original research in all fields of theoretical and applied mechanics. The Journal especially welcomes papers that are related to recent technological advances. The contributions, which may be analytical, experimental or numerical, should be of significance to the progress of mechanics. Papers which are merely illustrations of established principles and procedures will generally not be accepted. Reports that are of technical interest are published as short articles. Review articles are published only by invitation.
