Numerical analysis of the inclusion-crack interaction by the extended finite element method
TL;DR: In this paper, an extended finite element method (XFEM) is applied to study the inclusion-crack interactions in an elastic medium, and both the inclusions and the crack are modelled within the XFEM framework.

TL;DR: In this article, the authors investigated the benefits of a recently developed linear smoothing procedure which provides better approximation to higher-order polynomial fields in the basis, and observed that the stress intensity factors computed through the proposed linear smoothed extended finite element method is more accurate than that obtained through smoothed XFEM.
Journal ArticleDOI
Numerical estimation of stress intensity factors in cracked functionally graded piezoelectric materials – A scaled boundary finite element approach
TL;DR: In this paper, a semi-analytical technique is proposed to study the fracture parameters of functionally graded piezoelectric materials (FGPMs) subjected to far field traction and electrical boundary conditions.
Journal ArticleDOI
Construction of high‐order complete scaled boundary shape functions over arbitrary polygons with bubble functions
Journal ArticleDOI
Vibration of functionally graded material plates with cutouts & cracks in thermal environment
TL;DR: In this article, the effect of a centrally located cutout (circular and elliptical) and cracksemanating from the cutout on the free flexural vibration behavior of functionally graded materialplates in thermal environment is studied.
