Abstract:

In this paper, we present results on estimating material model parameters from inverse analysis of full-field deformation data obtained with a prototype of a novel integrated tool consisting of a digital image correlation system and software for data analysis and parameter estimation. Such a tool is needed for characterizing the properties of new materials, and for calibrating and validating material models. The stereo microscope-based image analysis system may be used for measurements at temperatures up to 750 deg C, and field sizes of approximately 1 mm. The Graphical User Interface GUI-based parameter estimation tool integrates image data analysis and inverse analysis modules, and incorporates features for interfacing the tool with commercial finite element FEM packages. Data analysis includes filtering or correcting for rigid body translations and rotations, and averaging for noise reduction.
