WebThe modified Drucker-Prager/Cap plasticity model (Modified Drucker-Prager/Cap model) can be used to simulate geological materials that exhibit pressure-dependent yield. The addition of a cap yield surface helps control volume dilatancy when the material yields in shear and provides an inelastic hardening mechanism to represent plastic compaction. WebDrucker–Prager yield criterion. Figure 1: View of Drucker–Prager yield surface in 3D space of principal stresses for. The Drucker–Prager yield criterion [1] is a pressure-dependent model for determining whether a material has failed or undergone plastic yielding. The criterion was introduced to deal with the plastic deformation of soils. 千葉県お祭り 2022 9月
