标题： Weight function approach to study a crack propagating along a bimaterial interface under asymmetric loading in anisotropic solids

摘要： 本文研究了沿异性正交各向异性材料界面稳态扩展的裂纹，在非对称载荷作用下。尽管迄今为止大多数已知结果处理的是对称载荷问题，但最近的研究表明，施加的载荷存在显著不对称性可能会导致应力强度因子（SIFs）值方面产生明显影响。本文的目的就是将这些结果从静态情况推广到移动裂纹情形。特别是，我们展示了载荷不对称性对于计算能量释放率的重要性。 显示英文摘要

摘要： This paper considers a steady-state crack propagating along an interface between dissimilar orthotropic materials under an asymmetric load. Although most of the known results so far deal with symmetric loading, it has been shown recently that a significant asymmetry in the applied loading may lead to a pronounced effect in terms of the values of the SIFs. The aim of the paper is to extend these results from the static case to a moving crack. In particular, we show the significance of the asymmetry of the loading for computing the energy release rate.
