Abstract

The effectiveness of a new photomechanical-numerical hybrid method for evaluating stress intensity factors (SIFs) in orthotropic composites is demonstrated. Reliable results are obtained from few moiré-measured displacements and they originate well away from the crak tip. The method is illustrated for the case of a uniaxially loaded orthotropic glass/epoxy composite containing a central, transverse crack.
