Dynamic Stress Wave Propagation
MetadataShow full item record
In an effort to provide an analyst with the fundamental knowledge required to successfully predict dynamic structural response, a detailed summary of dynamic stresses, review of dynamic pulse buckling and verified numerical examples are provided. The dynamic stress wave characteristics described herein, including strain-rate sensitivity, are reviewed within the literature with respect to dynamic pulse buckling. Many numerical studies within the literature utilize experimental studies to verify their approach to the dynamic pulse buckling problem. Several of the experimental studies utilized in the literature, were numerically analyzed herein and post-processed to provide a detailed investigation of stress wave propagation characteristics in impact problems of simple structures. The characteristics of stress wave propagation within a complex (ship double bottom) structure were investigated numerically. Several variations were observed between stress wave propagation within simple and complex plated structures.
