Finite Element Modeling of Strain Localization Initiated by Geometric Irregularities

The localization of deformation into zones of intense straining, known as shear bands, is a common phenomenon in inelastic deformation. The modeling of this phenomenon by the finite element method is hampered by a number of factors; the lack of a priori knowledge of the location, direction, and onset of the localized zones, and the inability of conventional isoparametric elements to model the high strain gradients which occur in these zones.
