Abstract
The dynamic response of a composite cylinder subjected to a moving pressure is investigated. The flexural wave in the wall of cylinder is modeled using both closed form analytic and finite element methods. Results indicate that very high amplitude and high frequency strains are induced in the cylinder at the instant and location of pressure front passage as the velocity of pressure front approaches the propagation velocity of the flexural wave. The dynamic amplification effects are especially critical for overwrapped composite cylinders because of the multi-material construction, anisotropy of material properties, thermal degradation of material properties, and the design goals inherent in lightweight structures applications.
