Generalization of the Wave Approach to the Analysis of Internal Equipment Response.
Abstract
A simplified method called the Transfer Function Technique (TFT) has been devised for evaluating the stress wave environment in a structure containing internal equipment. The TFT consists of following the initial in-plane stress wave that propagates through a structure subjected to a dynamic load and characterizes how the wave is altered as it is transmitted through intersections of structural members. As a basis for evaluating the TFT, impact and explosive experiments and detailed stress wave analyses were performed for structures with two or three, or more members. Transfer functions that relate the wave transmitted through an intersection to the incident wave were deduced from the predicted wave response. By sequentially applying these transfer functions to a structure with several intersections, it was found that the environment produced by the initial stress wave propagating through the structure can be approximated well. The TFT can be used as a design tool or as an analytical tool to determine whether a more detailed wave analysis is warranted. (Author)
