The purpose of the investigation was to study the gross effects of a thin cavity in a pressure bar. The experimental research was actually divided into two stages. The first one was devoted to the model research in materials, geometries, controlled measurements and loading methods. The second stage was to conduct experiments on the cavity bar to study the bar wave reflected and transmitted from the cavity section, the strain field approximate to the cavity region, the fracture mode, and the fracture strength.
