An optical microscopy study and a micro-Raman spectroscopy study were carried out on polyethylene samples subjected to an environmental stress crack resistance (ESCR) test. The aim was to elucidate the molecular deformation mechanisms associated with the failure process. It has been shown that in th
The following theoretical equation was obtained for the rate of initiation 6 of slow crack growth in polyethylene: where tr = applied stress, K = stress intensity, 7 = Poisson's ratio, E = Young's modulus, trc = stress to produce a craze, try = yield point, d = primordial thickness of the craze and
