Embodiment Construction

[0066] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0067] 1. A functional method for engineering material hardness determination, characterized in that, comprising the steps:

[0068] A. Measurement method of absolute hardness

[0069] According to the theory of action, the hardness is an unchangeable property that characterizes the point of action under the control of action, and the basic formula for measuring hardness is obtained as

[0070] T = 1 - x l ;

[0071] In the formula, T represents the hardness of the material to be tested, x represents the actual displacement of the affected point changing its relative position in the affected body under the control of th...

Abstract

The invention relates to an action science method for determining hardness of engineering materials, and belongs to the fields of basic theory and application technology of engineering mechanics. The method mainly comprises an absolute hardness measuring method, relative hardness, a relative hardness measuring method, and calculation of hardness by determination of resistance. The method has the beneficial effects that based on a new theory of action science, the problems existed in prior engineering material hardness concept definition, accuracy of calculating formula and determination results, uniformity of metric, reliability and the like are solved; the method widens roads for developing and improving basic theory science, basic theory applied science, and engineering material property science, and the industry for manufacturing hardness measuring tools is improved and developed.

Description

technical field [0001] The invention relates to an functional method for measuring the hardness of engineering materials, which belongs to the technical field of basic theory and application of engineering mechanics. Background technique [0002] In 1822, German mineralogist Friedrich Mohs proposed to use 10 kinds of minerals to measure the relative hardness of objects, that is, Mohs hardness, which is divided into ten grades from soft to hard: talc, gypsum, calcite, fluorite, apatite, orthoclase , quartz, topaz, corundum, diamond. The method of measuring mineral hardness with Mohs hardness tester is very simple. The predicted mineral and a certain mineral in the hardness tester will mark each other. If a certain mineral can scratch calcite, it means that its hardness is greater than that of calcite, but it can also be scratched by fluorite, indicating that its hardness is lower than that of fluorite. The hardness is between 3 and 4, which can be written as 3-4. Because t...
