Abstract
An application of multigrid techniques for the separation of principal stresses in plane stress systems is presented. By establishing the eq uilibrium equations and determining the value of shear from photoelast ic data a system of partial differential equations is obtained, which can be solved by applying a multigrid method. Multigrid methods are co mparable to Fourier methods in efficiency and robustness and can be ap plied to processing areas of arbitrary shape.
