# 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. The following topics are discussed:
