Title: Thermoelastic determination of individual stress components in loaded composites

An experimental-numerical hybrid method is developed for determining the individual stresses in orthotropic composites from measured thermoelastic information. This includes evaluating the thermoelastic calibration coefficients, effective processing of the noisy measured data, and separating the stress components at nonboundary locations. The method is illustrated experimentally by application to a uniaxially loaded fiber-reinforced composite plate containing a central circular hole. 39 refs.
