Abstract

The problem of multiple cracks originating at free surface (surface damage) in an anisotropic material is considered. We focus on the effect of material anisotropy on the mechanics of crack interactions – in particular, on the suppressing effect of interactions on crack nucleation and growth under the tensile loading (stress shielding). Importantly, this effect may change to the opposite one of enhancement, under the shear loading. These effects strongly depend on the material anisotropy. Calculations were performed for the orthotropic materials and the effect of anisotropy was examined by case studies of specific configurations that included comparison with the case of the isotropic material.

材料各向异性对表面损伤力学的影响

本研究考虑了各向异性材料中自由表面产生的多重裂纹（表面损伤）问题。我们将重点放在材料各向异性对裂纹相互作用力学的影响上--特别是在拉伸载荷（应力屏蔽）作用下，相互作用对裂纹成核和生长的抑制作用。重要的是，在剪切荷载下，这种效应可能会转变为相反的增强效应。这些效应在很大程度上取决于材料的各向异性。我们对正交材料进行了计算，并通过与各向同性材料进行比较的特定配置案例研究来检验各向异性的影响。

期刊介绍： The International Journal of Engineering Science is not limited to a specific aspect of science and engineering but is instead devoted to a wide range of subfields in the engineering sciences. While it encourages a broad spectrum of contribution in the engineering sciences, its core interest lies in issues concerning material modeling and response. Articles of interdisciplinary nature are particularly welcome. The primary goal of the new editors is to maintain high quality of publications. There will be a commitment to expediting the time taken for the publication of the papers. The articles that are sent for reviews will have names of the authors deleted with a view towards enhancing the objectivity and fairness of the review process. Articles that are devoted to the purely mathematical aspects without a discussion of the physical implications of the results or the consideration of specific examples are discouraged. Articles concerning material science should not be limited merely to a description and recording of observations but should contain theoretical or quantitative discussion of the results.
