Anisotropy of periodic microstructure in models of unidirectional composite materials

Original language description

In this paper a new algorithm for the generation of periodic microstructures with regular, irregular and random morphology is presented. It is used for the analysis of anisotropy of unidirectional continuous fiber-reinforced composite material. The generator algorithm is based on pseudo-physical model resembling the description of the mutual motion of particles in magnetic, gravitational or electrostatic fields with generally random attraction or repulsion forces and collision checking. The level or degree of irregularity of the generated periodic cells having the same fiber volume content is described using a recently proposed dimensionless parameter. The effective elastic constants and the stress concentration effect of the generated structures are numerically investigated using a large number of FEA models. A dependency between the degree of irregularity and the lower and upper limits of the effective parameters is demonstrated.
