Elastoplastic and fracture behaviour of semi-crystalline polymers under multiaxial stress states	2018	22	.pdf	application/pdf	12522	691	57	Qualitative SEM observations of HDPE fracture surfaces at several magnifications for flat notched specimens, R=5 and R=30, show the formation of an oriented texture of fibrous surface at the centre with a number of longer fibrils. HDPE fracture surfaces at RT and 50 °C have the same geometric patterns, however at 50 °C and at near surface appears a large number of microfibrils, indicating a continued plastically deformation as decohesion of crazing occurred.	cache/fis-2245.pdf	txt/fis-2245.txt
