...Yunhao Li; Qian Wei; Luxian Li Purpose We use the extended finite element method (XFEM) to model the whole process of initiation and propagation of cracks in the inner dense pyrolytic carbon (IPyC) layer of tri-structural isotropic (TRISO) particle induced by the microdefect in an irradiation...

...Ritesh Kumar; Himanshu Pathak; Akhilendra Singh; Mayank Tiwari Purpose The purpose of this paper is to analyze the repair of a straight and angular crack in the structure using a piezoelectric material under thermo-mechanical loading by the extended finite element method (XFEM) approach...

... source, and the welding heat source is the Gauss heat flux distribution. The extended finite element method (XFEM) is implemented to calculate and solve the AE response of a thermoelastic plate with a crack during the welding heating effect. The wavelet transform is applied to the time–frequency analysis...

... configuration. This paper provides detail mathematical frameworks of XFEM procedures having multiple intersecting discontinuities (from now on, they will be termed as joints) in rock masses. The intersection of joints having traction-closure relationship is formulated in such a way that no additional...
