Paper Abstract

Two optical moire methods for curvature measurements are presented: a) A new method was developed, based on projection moire, in which the fringes relate directly to the second derivative of displacement. The method was applied on cylindrical shell segments (CSS). b) Rasterography was extended for the measurement of changes in the radius of curvature. It was also demonstrated here for CSS, under static loading. The two methods were examined and compared with theory and strain gauge measurements, and were found to be with similar results.
