Abstract

Thermoelastic stress analysis and grey-field photoelasticity are combined with the Laplace and Beltrami-Michell equations to non-destructively evaluate the individual internal components of stress in a loaded 3-D aluminium member. Experimental results agree with those predicted numerically by the finite element and finite difference techniques.
