摘要： A combined analytical and numerical method is proposed for computation of mixed-mode stress intensity factors (SIFs) for arbitrary curved cracks in anisotropic functionally graded materials (FGMs). By developing a pair of closed-form expressions that relate the SIFs and the J k -integrals, it is anticipated that the SIFs can be properly extracted should the J k -integrals be accurately evaluated. To this end, a novel method for calculating the J k -integrals is presented and has proved reasonably accurate in numerical computations. Since neither a priori information nor extra auxiliary solutions corresponding to the singular behavior is required, this proposed scheme appears to be applicable to problems containing arbitrary shapes of curvature in generally anisotropic FGMs. 出版者： Taylor & Francis 出版日期： 2013-12-01 出處： Journal of the Chinese Institute of Engineers, 2013-12, Vol.36 (8), p.1045-1058 版權： 2013 The Chinese Institute of Engineers 2013 識別號： ISSN: 0253-3839 識別號： EISSN: 2158-7299 識別號： DOI: 10.1080/02533839.2012.747048
