Samenvatting

A common practice in toughening semicrystalline polymers is to blend them with second-phase rubber particles. A multiscale numerical model is used to investigate the effect of a specific microstructural morphology on the mechanical behavior of particle-dispersed systems. A polycrystalline model is used for the polymer matrix material. The basic structural element in this model is a layered two-phase composite inclusion, comprising both a crystalline and an amorphous domain. The averaged fields of an aggregate of composite inclusions, having either random or preferential orientations, form the constitutive response of the polymeric matrix material. Transcrystallized orientations are found to have a limited effect on matrix shear yielding and alter the triaxial stress field.
