Elementary Volume Concept - a new modelling approach to calculate elastic moduli of spherical composites systems introducing the interfacial adhesion

Popis výsledku v původním jazyce

The Elementary Volume Concept (EVC) is a new modelling approach, which assumes that a single Elementary Volume (EV) consisting of a matrix part and a composite part can be used to reproduce mechanical performance of a spherical composites system (SPS). PAUL and ISHAI-COHEN models tend to over- and under-estimate the experimental data, respectively. This can be overcome by the introduction of an adhesion coefficient in the EVC, which reduces the effective area of load transfer between filler and matrix. The adhesion coefficient was evaluated qualitatively using scanning electron microscope (SEM) images of generated fracture surfaces under cryogenic conditions of the respective specimen.
