    Enhancement of Drucker-Prager yield model by adding corner points for pressure-dependent materials

    To flexibly describe the pressure-dependent behaviors of materials, Drucker-Prager yield model is enhanced by introducing corner points. We call it piecewise Drucker-Prager (pDP) yield model. Constitutive mode...
