| Abstract: | In this paper the stress analysis of the plane stress field in a shrunkon disc is presented using the principle that the velocity change of longitudinal and transverse sound waves is proportional to the sum of the principal stresses in a state of plane stress and the difference between principal stresses. The experimental data are compared with the theoretical results and some suggestions for improvement are made on the major problems with the method. |
