摘要：

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 co-efficients, 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.
