چکیده

The effective conductivity of 2D double periodic composite materials with circle disjoint inclusions is investigated. Ideal and non-ideal contact conditions on the boundary between the matrix and the inclusions are considered. In both cases, explicit formulas for the effective conductivity are obtained. These formulas contain all parameters of the considered model such as the conductivity, radii, centers of the inclusions, the conductivity of the matrix, and also special Eisenstein functions. Based on the explicit formulas, the effect of perturbation of the inclusion in the case of ideal contact conditions is also investigated. It is found that any random motion of the inclusions increase the effective conductivity in the case when the conductivity of the inclusions is greater than the conductivity of the matrix.

Review of Damage Tolerant Analysis of Laminated Composites

With advanced composites increasing replacing traditional metallic materials, the material inhomogeneity and inherent anisotropy of such materials lead to not only new attributes for aerospace structures, but also introduce new technology to damage tolerant design and analysis. The deleterious effects of changes in material properties and initiation and growth of structural damage must be addre...

Three-dimensional microvascular fiber-reinforced composites.

Living systems rely on pervasive vascular networks to enable a plurality of biological function in both soft and hard tissue. Extensive vasculature in composite structures, such as osseous tissue in bone and tracheary elements in trees, exemplify natural materials that are lightweight, high-strength, and capable of mass and energy transport. In contrast, synthetic composites possess high streng...

Computational evaluation of the homogeneity of composites processed by accumulative roll bonding (ARB)

A new computational method based on MATLAB was used to study the effect of different parameters on the homogeneity of composites produced by a severe plastic deformation technique known as accumulative roll bonding. For a higher number of passes, the degree of particle agglomeration and clustering decreased, and an appreciable homogeneity was obtained in both longitudinal and transverse directi...
