In inverse finite element-based analysis, complete experimental data collection is critical for multi-parameter identification and physical modeling of all kinds of materials. In this paper, diffraction-assisted image correlation (DAIC) is improved and proposed for the deformation measurement of a soft material under indentation with no blind area. A simple and convenient image-based 3D calibration...
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...
