Abstract

An embodiment of the invention provides a method and system to measure surface mechanical properties of a metal material, wherein the method includes: acquiring apparent stress of each measurement point on the surface of a metal material under measurement; inputting the apparent stresses of the measurement points into a pre-constructed model; acquiring yielding strength of the surface of the metalmaterial under measurement according to output results of the pre-constructed model, wherein the pre-constructed model is used for indicating correspondence between the apparent stresses of the measurement points and the yielding strength. The method and system according to the embodiment allow the mechanical properties of the surface and near-surface of a metal material to be accurately measured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of material analysis and testing, and in particular to a method and system for measuring the mechanical properties of the surface of metal materials. Background technique [0002] Cleaning technology is an indispensable technology in many fields such as industrial production and artwork protection. However, the traditional cleaning technology has defects such as damage to the substrate, pollution to the environment and insufficient precision. The green and environmentally friendly laser cleaning technology is a new type of cleaning technology that has developed rapidly in the past 10 years. With its many advantages, it has gradually replaced the traditional cleaning process in many fields, showing broad development prospects. my country's laser cleaning technology started late, and most of them are still in the experimental stage. In order to better realize industrialization, it is...
