1 December 1991 Dynamic photoelasticity applied to crack-branching investigations
Author Affiliations +
Experimental investigations of crack-branching on central-notched plates in polymer are presented using dynamic photoelasticity. From a multiparameter representation of the stresses around the crack-tip, the stress-intensity factor is determined by a multiple-point method which couples iterative process and minimization procedure. The experimental device (high-speed camera, loading system) is described and the results are discussed. The polymer tested seems to correlate with the macroscopic branching criteria commonly found in dynamic fracture analysis.
