An anisotropic elastic-viscoplastic constitutive model is developed for K0-consolidated soft clays in general stress space. Two surfaces are assumed to exist for any loading stress as the loading surface and the reference surface. The scalar mul[...]

This article presents some aspects of continuous assumed gradient (CAG) methods applied to explicit structural dynamics. CAG elements are finite elements in which the strain (i.e., the deformation gradient) is replaced by a C0-continuous interpo[...]
