The present work studies the influence of Maxwell stress on a straight but non-linear polarization saturation (PS) crack in a 2D piezoelectric material under combined mechanical and electric loadings at infinity. The non-linear piezoelectric fracture mechanics model, which is the PS model, is adopted in this paper. It is assumed that the crack is electrically semi-permeable. Based on the Stroh's formalism...
Based on complex variable method, this work studies the two dimensional problem of a sharp elliptic hole/crack in an infinite soft ferromagnetic medium which is subjected to the remote magnetic loads. Emphasis is placed on the investigation of the effects of the applied magnetic loads on stress concentration around the elliptical hole and the intensity factor of stress, k, when the hole degenerates...
