The effects of dilatancy in composite assemblies as micropolar continua

Dilatancy is of importance for understanding the micromechanical behavior materials such as cemented sand, mortar joints, and interfaces masonry-like structures. Rough interface contacts are able to result in dilatancy lead an increase material’s volume. However, far authors’ knowledge very few works present regarding phenomenon composite materials. The work aims at investigating effect on with rigid particles connected by rough elastic interfaces. Different hexagonal shapes considered a series geometric parameters. stiffness properties can be obtained employing statistical distribution function roughness termed contact density model. A homogenization procedure based energetic equivalence criterion used derive constitutive homogenized continuum results micropolar additional degree freedom (the microrotation) known give effective modeling micro-structures. 2D plane slope composed material various analyzed under dilatancy. This study shows validity theory when considering microstructure, which essential capturing more realistic
