This paper presents a method to identify the material parameters of a thermo-mechanical constitutive model using the temperature profile observed in a material during fatigue loading. The temperature profile observed during loading is a function of the damage accumulated in the material and can provide valuable information for the prognosis of material state. Accumulated low cycle fatigue tests were carried out on stainless steel SS304 specimens and the temperature was measured using infrared thermography. The experimental data was then used to show the change in material state through the identification of material parameters. © 2011 American Institute of Physics.
