Abstract

The simultaneous and accurate identification of multiple thermo-mechanical parameters of superalloy materials in complicated service condition is an important and difficult problem. In this paper, an integrated digital image correlation (I-DIC) method was developed to address this issue. For the first time, thermo-mechanical deformation was inversed and decoupled by using I-DIC combined with an inhomogeneous high-temperature thermo-mechanical loading and optical band-pass filter imaging system. Results show that the proposed method has advantages such as high independence, short computing times, easy operation, and a small probability of error accumulation. Therefore, I-DIC is an effective and promising tool for multi-parameter inversion and thermo-mechanical deformation decoupling in practical engineering conditions.
