摘要

A NASTRAN computer program is developed to model the one-dimensional stress-wave propagation in a viscoelastic bar exhibiting temperature-dependent material properties. Verification experiments were performed on methylmethacrylate rods with different temperature distributions and lengths by impacting the instrumented rod with an air-gun-launched projectile. The computer program is considered to be essential to the design of rain-erosion-resistant radomes for extended range artillery fuzes. (Author)
