Embodiment Construction
[0091] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0092] In the prior art, the plane stress is measured in a certain measurement direction based on the circumferential magnetic Barkhausen noise. The measurement result obtained by this method is only the stress component of the stress on the material in this direction. If the stress is directly measured The component will be greatly deviated or ev...
