Effects of Temperature-Dependent Material Properties on Stress and Temperature in Cracked Metal Plate under Electric Current Load

Authors: Thomas Jin-Chee Liu


Using the finite element analyses, this paper discusses the effects of temperature-dependent material properties on the stress and temperature fields in a cracked metal plate under the electric current load. The practical and complicated results are obtained when the temperature-dependent material properties are adopted in the analysis. If the simplified (temperature-independent) material properties are used, incorrect results will be obtained.

Keywords: finite element, crack tip, Joule heating, temperature-dependent
