Abstract:	摘要： AbstractA numerical method is proposed for calculation of the mixed-mode stress intensity factors at a crack tip in anisotropic functionally graded materials (FGMs). The method is constructed by introducing the nonhomogenized displacement discontinuities technique. With this method, the stress intensity factors can be effectively determined by direct use of the finite-element results of the near-tip displacement discontinuities across the crack surfaces. The result from the proposed method can also be used as an effective indicator for evaluating the accuracy of the calculation. This proposed approach is applicable for problems containing curved cracks of arbitrary shape in general anisotropic FGMs. 出版者： American Society of Civil Engineers 出版日期： 2014-12-01 出處： Journal of engineering mechanics, 2014-12, Vol.140 (12) 版權： 2014 American Society of Civil Engineers. 識別號： ISSN: 0733-9399 識別號： EISSN: 1943-7889 識別號： DOI: 10.1061/(ASCE)EM.1943-7889.0000799
