THERMOELASTIC RESPONSE OF METALS AT DIFFERENT LOADING RATES

Abstract

This paper deals with the thermoelastic response of ferrous and non-ferrous metals at different loading rates. The goal is to predict the stress-strain response based on temperature changes caused by adiabatic processes. These data are intended to be used for non-destructive full-field thermal stress analysis (TSA). The influence of strain rate on temperature was investigated in cyclically loaded dog-bone shape specimens with initial and reduced thicknesses under sinusoidal-profile loads. Testing parameters, such as the load magnitude and frequency were chosen with respect to the specimen design and the results of tensile tests. The dependence of thermoelastic properties of metals on loading rate was found at frequencies between 0.005 and 1 Hz. Temperature changes at various loading rates are presented and discussed.
