Abstract:Wire rope reinforced composites have many technologically important applications. These composites are used in automobile tires, conveyer belts, and various military components. This particular combination of materials is especially effective when the composite material needs to be strong in tension in a particular direction, but also needs to be flexible and bend easily out-of-plane.
These composites are typically treated using classical lamination theory, where the unidirectional lamina is considered to be orthotropic. However, the internal structure of the wire rope couples the extensional and twisting modes, even in the unidirectional case. Two new theories, an equilibrium based plate element model and an energy method model are developed to include this coupling. The energy method model development is extended to incorporate Kirchhoff, linear shear, or cubic shear plate theories. These models are used to investigate the global response of one-layer and two-layer plates as a function of cord angle and cord volume fraction. These results are compared to the results of classical orthotropic lamination theory to evaluate the suitability of the various theories to these composites.
