| Research Abstract |
In this research the following have been investigated.
1.The effect of the distance from a shock pressure source to the specimen on the accuracy of punching a hole.
2.Relations between materials and accuracy of punching a hole.
3.Applications of the results of static punching by high pressure to setting appropriate conditions for punching with underwater shock pressure.
4.Development of a computer program for numerical simulation, by which the mechanism of shearing deformation of a metal plate is analyzed.
5.Trial production of a new device to generate underwater shock pressure using the high speed forming chamber.
6.Possible size, shape and number of holes, which are punched on the wall of metal pipes.
