A recently developed method for enhancing the performance of general classes of elements in strain localization problems is reviewed. The method exploits information concerning the process of localization which is readily available at the element level. The method can be applied to two dimensional and three dimensional problems involving a broad class of rate independent and rate dependent material behaviors. Numerical examples illustrate the ability of the method to resolve localized failure modes to the highest resolution allowed by the mesh.
