The Winfrith Concrete Model : Beauty or Beast ? Insights into the Winfrith Concrete Model
This introductory document describes the basic plasticity model, the strain rate formulations and tensile cracking options. The *MAT_WINFRITH_CONCRETE model is another of the so called LS-DYNA ‘simple input’ concrete models, that ...

The RHT concrete model in LS-DYNA
The RHT concrete model is implemented in LS-DYNA. It is a macro-scale material model that incorporates features that are necessary for a correct dynamic strength description of concrete at impact relevant strain rates and pressures. ...
