Approximation of the Temperature and Time Dependence of the Stress versus Rupture Life Curves by Power Functions
This paper explains and demonstrates an approximation method for the calculation of the stress values depending on the temperature and time, or time values depending on the stress and temperature using time dependent and temperature dependent power functions. The approximation is based on measured data and the paper shows the verification of the power function approximation.
