Most automobile interior parts consist of plastic components. These components must satisfy several criteria, including the thermal-cycle resistance, vibration resistance, and impact resistance. The automobile industry is working to reduce the thermal deformation that occurs through periodical, seasonal changes. Essential material properties for thermal deformation simulation were acquired under various temperature conditions, such as stress-strain curve, dimensional change curve during thermal expansion and creep. It is necessary to obtain the material properties for thermal deformation analysis under the heat cycle test. Specially, creep data of plastic material was introduced to study the time-dependent deformation behavior of the instrument panel in heat cycle test. The test has been fitted into a time-hardening type creep constitutive equation. The time-hardening version of the power-law creep model was applied to account for the permanent deformation after heat cycle test, verified through the comparison of test result with FEA result for creep model.
