Abstract

This chapter describes a new method used for non-destructive measurement of arbitrary 3D state of stress using photoelasticity. The new approach, namely, load incremental approach, is an attempt to solve the nonlinear inverse problem of 3D photoelasticity by considering small change in a state of stress for a small load increment. Thereby, linearizing the nonlinear governing equation of photoelasticity. As long as the applied load increment is small and photoelastic images are taken with high resolution in load increment, this method works and can reconstruct arbitrary 3D stress state.
