Abstract
Individual stresses in an elliptically perforated graphite/epoxy laminated composite are determined from recorded load-induced thermal (TSA) information. Equilibrium and compatibility conditions are satisfied using complex-variable formulation, conformal mapping and analytic continuation. Processing the measured thermal data with a stress function simultaneous smooths the recorded information and evaluates the individual stress components, including on the edge of the hole. Experimental results agree with those from FEM and force equilibrium.
