| Abstract: | Based on the analysis of the existing non-destrutive testing method, the vortex testing method was proposed to do the non-destructive detection of defects for pressure vesselsin service.The distribution and the change law of the vortex field with cracking structure were simulated through FEM. The result shows that the vortex testing method had an evident advantage in testing the fatigue cracking of pressure vessels in service. |
