Abstract
When an elastic rod, under the influence of a large temperature variation, is used as a stress-pulse measuring device, pulse distortion may result due to the variation with distance of the elastic wave speed. An example of rod non-homogeneity, which is particularly adaptable to analysis, is considered in this paper. A semi-infinite elastic rod, with propagation speed c(x), is subjected to a pressure step at its end. The pulse wave shape is examined for a rod in which c(x) has a parabolic distribution over a portion of the rod and is constant over the remainder.Keywords
