Research output: Contribution to journalArticle


Moire interferometry was utilized to study fracture behavior of polymer specimens under mode I loading. Displacement fields around a crack tip were experimentally determined for two kind specimens of brittle and ductile polymers. The results were compared with the displacements given by linear fracture mechanics or HRR fields to study their applicability to the polymers. Examinations were also made on the effect of material properties and the influence of load applied to the specimens.
