HYBRID STRESS-ANALYSIS OF FLEXED ISOTROPIC AND COMPOSITE PLATES

An effective numerical-experimental hybrid method is formulated and demonstrated for stress (strain) analyzing flexed isotropic and composite plates. Measured transverse displacements are represented and differentiated analytically, while the number of unknown coefficients, amount of experimental input data needed and computational time (costs) are reduced by imposing equilibrium and boundary conditions. The approach is accurate, full-field, employs arbitrarily shaped elements and is well suited for computer vision techniques.
