Abstract

In previous paper, cracks of welds under repeated loads were investigated with changing the opening displacement at groove. It suggested the repaire's methods of welds in the case of crack's occurrence. In this paper, cracks of welds under repeated loads are investigated with changing repeated frequency and groove angle. The results of the experiment are reported.
