Jassim, Widad	The Energy of Break or Deformation in Some Semi- Crystalline Polymers	2017	9	.pdf	application/pdf	1826	94	67	The energy to break or deformation was determined as a function of extension rates , ( PP) was break at extension rate (5) mm/min but (HDPE) break at higher extension rates (25) mm/min while( LDPE) not break even at very high extension rates but it is deformation or failure .	cache/iajs-187.pdf	txt/iajs-187.txt
