Abstract
The question of the domain of dominance of the plane-stress asymptotic elastic fields in dynamic fracture is addressed for the two cases of dynamically loaded stationary cracks as well as dynamically propagating cracks. A new optical configuration is proposed which would allow for the simultaneous measurement of the apparent dynamic stress-intensity factor from two different regions around the crack-tip using the method of caustics. The results of the study indicate the importance of three-dimensional and transient effects in the interpretation of optical measurements.
