Hydrodynamic Analysis Materials

The following material laws are commonly used for fluid simulations:
  • Johnson-Cook model for strain rate and temperature dependence on yield stress (LAW4),
  • Hydrodynamic viscous material for Newtonian or turbulent fluids (LAW6),
  • Elasto-plastic hydrodynamic materials with von Mises isotropic hardening and polynomial pressure (LAW3),
  • Steinberg-Guinan elasto-plastic hydrodynamic law with thermal softening (LAW49),
  • Boundary element materials (LAW11),
  • Purely thermal materials (LAW18)

Radioss provides a material database incorporated in the installation. Many parameters are already defined by default and give accurate results.
