Abstract In this work, two fracture modelling methods i.e., extended FEM (XFEM) and localizing gradient damage method (LGDM), are combined to get the advantages of both methods while eliminating their limitations. The LGDM is a micromechanics-based method that avoids spurious damage growth and incorrect damage initiation observed in conventional gradient damage method (CGDM). However, in the LGDM, a cracked/discontinuous domain is not fully realized due to its continuous nature, even at high dam...

Magnetic nozzles with their contactless feature have opened new grounds for long-distance space travels. For quicker mission completions along with improving system reliability, it becomes necessary to design robust systems that exhibit the ability to confine thrust. A semianalytical numerical method is proposed for rapid and assumption-less calculations of the magnetic field because of a thick coil with rectangular cross section. The method is extended for the proposal of a three-coil setup, wh...

This work presents a framework to study the quasi-static brittle fracture in functionally graded materials with random material properties using a non-intrusive phase field method. The model accounts for variation in the material and fracture properties. Further, the effective Young’s modulus, the gradient index and the fracture properties of the constituent materials are considered as random input variables. The output randomness is represented by polynomial chaos expansion. Two-dimensional ben...

Abstract In this work, we present an extended isogeometric analysis (XIGA) for cracked functionally graded magneto-electro-elastic (FGMEE) material. The material properties inside the FGMEE domain vary exponentially. An electrically and magnetically impermeable crack in the FGMEE domain is modeled by adding appropriate enrichment functions into the isogeometric analysis (IGA) approximation. Heaviside function is utilized to model the displacement, electric, and magnetic potential along the crack...

Abstract In the present work, the extended finite element method (XFEM) is successfully implemented for the thermo-elastic analysis of edge dislocations. Volterra type edge dislocation is modeled using Heaviside and core enrichment functions. The singularity at the dislocation core is captured through infinite domain solution at the core. The Peach-Koehler force is numerically evaluated using the domain form of the J-integral from the XFEM solution of thermo-elastic fields. Two problems i.e. an ...
