유한요소법에 의한 용접부에서의 응력파의 수치해석

초록

In this study, the propagation of the stress waves by the shock loading on the weld zone is simulated through the simplified F.E.model. For this purpose, the accuracy of F.E. also is checked up by comparing the results of stress wave propagation on a plate with the results of photoelastic experiment and the result of F.D.A which uses the bicharacteristic method. Finally, the explosion treatment method is introduced to reduce the residual stresses.
