A new method for non-destructive measurement of arbitrary 3D stress state using photoelasticity has been developed. The new approach, namely, load incremental approach, is an attempt to solve the nonlinear inverse problem of 3D photoelasticity by considering change in stress state for a load increment and linearizing the nonlinear governing equation. 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.
