Polymer Science: A Comprehensive Reference
Semicrystalline polymers often show a spherulitic morphology, consisting of a radial assembly of twisted crystalline lamellae and amorphous layers. A multiscale numerical model is used to investigate the mechanics of intraspherulitic deformation of polyethylene. The model establishes links across the microscopic, the mesoscopic, and the macroscopic levels. Constitutive properties of the material are identified for the crystallographic and amorphous domains. The averaged fields of an aggregatedoi:10.1016/b978-0-444-53349-4.00011-x fatcat:ytb634zqjngevg57tpyzzdhif4
