Embodiment Construction
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0047] The invention provides a method for measuring the evolution law of the dynamic stress field of a complex heterogeneous structure, so as to solve the problem that the existing digital photoelastic method cannot realize that the complex structure is continuously loaded with a relatively high external load under the condition of a fixed light field. The problem of global stress field extraction and quantification.
[0048] Specifically, for the measurement method of the evolution law of...
