Embodiment Construction

[0036] figure 1 , 2 , 3 are the mesoscopic deformation substructure images a, b, c of a group taken out at a certain (time) and (strain) interval in the continuous mesoscopic mechanical test, from a→b time, the mesoscopic deformation substructure images There is a change in the structure, and there is an uneven rotation in the entire observation field of view (inside the takeover image). This test method analyzes and calculates a→b, and the rotation amount change field diagram a→b at time, diagram b→c and Table (1) The deformation spinor field data file shown.

Abstract

The invention belongs to the field of material deformation. The invention uses a digital camera to shoot the whole field photos; the two front and back frames of the whole field images or continuous multi-frame images are taken out; relevant image recognition software is used to carry out memorizing and relevant recognition on the images; the deformation spinor characteristic parameter analysis for each point of the whole filed is calculated by a spinor field computing formula; then measurement is carried out to obtain various cartoon documents and data. The invention carries out calculation and analysis on the deformation spinor field of the whole field to give out the value and the direction of the rotating spinor field of each part of the whole field during the cracking process of the deformation of a material; the invention is a novel creation in the field of metal physics.

Description

technical field [0001] The invention belongs to the field of material deformation Background technique [0002] At present, in the field of sample measurement of real-time sample surface dynamic topography in Russia, there is no analysis and observation of the full-field deformation spinor field at any stage. The deformation spinor field is an important measure of material deformation damage. There is no such Very valuable mesomechanics research information will affect the level of research. Contents of the invention [0003] The purpose of the present invention is to obtain this very valuable mesoscopic mechanics research information by calculating and analyzing the comprehensive deformation spinor field at any stage of the sample observation area of ​​the real-time dynamic topography of the sample surface. [0004] The present invention uses a digital camera to take a full-field photo, takes out two frames of full-field images before and after, or continuous multi-frame...
