The Stochastic Interface Defects in Composite Materials Subjected to Aging Processes

ABSTRAKT

The main objective of this work is to propose a brand-new stochastic model of the interface defects appearing frequently between composite components. This model is based on the semicircular idealization of those defects and stochastic approximation of materials’ aging processes. Then, the stochastic interface defects so defined are located within the artificial interphase inserted between the existing constituents, the material properties (their probabilistic moments) of which are determined from the stochastic averaging rule. This interphase with the stochastic geometry and the stochastic material properties enables for further numerical homogenization of this composite in the microscale, if only a distribution of the assumed defects has the same probabilistic properties in each representative volume element.
