Adiabatic analysis

An adiabatic stress analysis:

  • is used in cases where mechanical deformation causes heating but the event is so rapid that this heat has no time to diffuse through the material—for example, a very high-speed forming process;

  • can be conducted as part of a dynamic analysis (Implicit dynamic analysis using direct integration or Explicit dynamic analysis) or as part of a static analysis (Static stress analysis);

  • in Abaqus/Standard is available only for the isotropic hardening metal plasticity models with a Mises yield surface (Classical metal plasticity);

  • in Abaqus/Explicit is relevant only for the metal plasticity models (including both Mises and Hill yield surfaces);

  • can be conducted if parts of the model are elastic only—no change in temperature occurs in the elastic regions; and

  • requires that a material's density, specific heat, and inelastic heat fraction (fraction of inelastic dissipation rate that appears as heat flux) be specified.
