| Abstract: | The magnetic strain method is nondestructive testing technology based on the magnet- ic anisotropy effect; it is very suitable for the welding residual plane stress measurement of high risk equipments especially for pressure vessels, due to its non-destructive feature and green envi- ronmental protection etc. This paper describes a research progress of magnetic plane strain algo- rithm, and analyses its current doubt and problems. |
