WitrynaFor the hypoplasticity model, its integration-based nonlocal regularization is also implemented to alleviate the mesh dependence problem, and the thery is documented in Wójcik and Tejchman, 2009. Instructions for Software Configuration WitrynaA new version of a hypoplastic constitutive equation is presented which is characterized by the introduction of a stress‐like internal parameter called back stress. The back stress is a function of the void ratio and of the hydrostatic stress.
