Elements with embedded localization zones for large deformation problems

Abstract A finite element which embeds a localization band within the element by means of an assumed strain formulation is described in the context of a general nonlinear theory. This element allows the treatment of shear bands which are much smaller than the element size, and hence is called a sub-h localization method. Results obtained by this method show that the stiffness of the element depends strongly on the angle of the band and its width, and that the magnitude of the softening increases with decreasing width of the shear band.
