Paper Abstract

Strains under three dimensional deformation are determined from holographic interferometric fringe. For a cantilever beam subjected to the combined forces of out-of plane and in-plane deflection, holographic interferometric fringes are obtained experimentally. From a fringe pattern, the effect of the out-of plane deflection and the in-plane deflection are analysed, respectively. The 3rd order polynomial of displacement distribution is obtained using regression method. Therefore strain can be determined from the second derivative of the polynomial. The experimental result is compared with the numerical analysis by finite element method.
