The Energy of Break or Deformation in Some Semi- Crystalline Polymers
Abstract
The aim of the current study is the investigation of tensile behavior of the semi -crystalline polymers : polypropylene (PP ) , high density polyethylene(HDPE) and lowdensity polyethylene (LDPE) .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 deformationor failure
