Development of Strain Field Estimation Method from CT Images Using Image Correlation Technique

Abstract

The purpose of this study is to estimate strain field from the time series of 3-D CT image. Texture analysis is utilized for distinguish whether the interested region has pattern or not. Image correlation procedure identifies displacement vector field for each “having pattern” region. Governing equation of linear elastic body, i.e., FEM analysis estimates displacement vector field for the rest domain. In this paper, numerical examples in 2-D case are shown.
