Birefringent coating stresses and strains

WebFor plane stress in elastic bodies, accuracy of stress or strain determinations along free boundaries is almost entirely independent of coating thickness; however, where Poisson's ratios of coating and structure are unequal, the state of stress in the structure might be influenced by the presence of the coating. WebA method is proposed which allows for the reinforcing effect of a birefringent plastic coating used in assessing strains in a loaded metal structure by photoelastic …
