In the present work, a comparative analysis has been presented between linear elastic and elasto-plastic fracture modelling of ductile structures using extended finite element method (XFEM). Three different fracture models ...

Multiple cracks/voids have been extensively seen in structural components. The stress field gets affected due to the crack interaction, so the effect of multiple cracks should be considered in design analysis. Further, ...

In this paper, a new enrichment scheme is employed in conjunction with XFEM for the stable crack growth analysis in ductile materials. In the proposed enrichment scheme, only Heaviside enrichment function is used with the ...
