Thermal expansion

Thermal expansion effects:

  • can be defined by specifying thermal expansion coefficients so that Abaqus can compute thermal strains;

  • can be isotropic, orthotropic, or fully anisotropic;

  • are defined as total expansion from a reference temperature;

  • can be specified as a function of temperature and/or field variables;

  • can be defined with a distribution for solid continuum elements in Abaqus/Standard; and

  • can be specified directly in Abaqus/Standard in user subroutine UEXPAN or in Abaqus/Explicit in user subroutine VUEXPAN if the thermal strains are complicated functions of temperature, time, field variables, and state variables.
