Mixed stabilized finite element methods in nonlinear solid mechanics Part II: Strain localization

This paper deals with the question of strain localization associated with materials which exhibit softening due to tensile straining. A standard local isotropic Rankine damage model with strain-softening is used as exemplary constitutive model. Both the irreducible and mixed forms of the problem are...
