Abstract
In this paper, an XFEM-based framework is presented to model the semipermeable crack in magneto-electro-elastic (MEE) material. The interaction-integral technique is modified and implemented to extract the normalized magnetic induction intensity factor (MIIF). The complex eight-fold enrichment functions are used in XFEM to capture the singular fields at the crack tip in semipermeable MEE media. The proposed numerical model is validated with the reference solution available in the literature. Numerical simulations also are performed to study the effects of poling direction, far-field loading, and electric–magnetic tractions on normalized MIIF.
