Transverse Loading of Unidirectional Fiber Composites
Abstract
The study is a part of an effort being directed toward solving the problem of a composite material subjected to general oblique loading. This analysis was conducted in order to find the internal micromechanics of a fiber- reinforced composite due to transverse normal loading. Special emphasis was given to studying the stress distribution near free surfaces, which led to solving a three-dimensional elasticity problem. The numerical method of finite elements was employed in this analysis. On the other hand, it was necessary to study the behavior far from free surfaces. For this purpose, a two-dimensional program was used. Findings from these two approaches were anticipated, showing that stress conditions become two dimensional a relatively short distance from the end of the composite. Extensive parametric studies were performed from the combined outputs of these two schemes. Significant diagrams exhibiting elastic properties of different composite materials were obtained.
