Description

The problem which we investigate here arises from our earlier results [1] which are reproduced in Fig. 1. This figure shows the upper surface and lower surface normal displacement for three different fiber composite laminates due to a line load impact acting on the upper surface in each case. The laminates are constructed of layers of the same fiber composite material, perfectly bonded together. Each layer consists of a family of parallel strong elastic fibers lying in the plane of the layer and embedded in an isotropic elastic matrix. The three laminates to which the results in Figure 1 relate are a symmetric four-ply plate with (90°/0°) s configuration, a six-ply plate with layers arranged in a (−60°/60°/0°) s configuration and a quasi-isotropic eight-ply plate with layer configuration (90°/ −45°/45°/0°) s.

Reflection and Transmission Phenomena for Transient Stress Waves in Fiber Composite Laminates

La Jolla, CA

The problem which we investigate here arises from our earlier results [1] which are reproduced in Fig. 1. This figure shows the upper surface and lower surface normal displacement for three different fiber composite laminates due to a line load impact acting on the upper surface in each case. The laminates are constructed of layers of the same fiber composite material, perfectly bonded together. Each layer consists of a family of parallel strong elastic fibers lying in the plane of the layer and embedded in an isotropic elastic matrix. The three laminates to which the results in Figure 1 relate are a symmetric four-ply plate with (90°/0°) s configuration, a six-ply plate with layers arranged in a (−60°/60°/0°) s configuration and a quasi-isotropic eight-ply plate with layer configuration (90°/ −45°/45°/0°) s.
