Název v původním jazyce

Computational estimation of micro-crack behaviour in polypropylene copolymer

Popis výsledku v původním jazyce

Polymeric particulate composites are frequently used in many engineering applications. The composite was modeled as a three-phase continuum-matrix, interphase and particle. The presence of particles significantly influences the cure reaction, resulting in the formation of the third phase known as the interphase, which possess property distinct from those of the matrix and the particle. Computation of the internal stress and strain fields in the micro-structural level of the studied composite and understanding of micro-cracks behaviour in the interaction with particles is the first step to understanding the global behaviour of the composite based on micro-structural morphology. Therefore, particle reinforced composite has been modelled as a three-phasematerial with homogenously distributed coated particles and numerically studied on the microscopic scale using finite element modelling.
