Action-logy method of material property measurement and measurement instrument therefor

Abstract

The invention relates to an action science method for measuring material properties and a measuring instrument thereof, belonging to the research fields of theoretical mechanics, applied mechanics and experimental mechanics. According to the theory of action, the deformation is not only related to the size of the force, but also related to the size of the action, and the basic law equation for studying the deformation is obtained as It can be obtained by measuring the value of each parameter: the general relationship law of stress-strain relationship, the unified relationship law between ultimate stress and stress, solidity, and void, the maximum action that the material can resist without deformation within a certain time limit, and the solidity of the material The value research method of the sum of emptiness and its change law, emptiness and solidity. The beneficial effects of the present invention are: based on the functional theory, a new theory and a new formula for the study of material variable strength and void or solidity are given; a new theory of the relationship between material strength, action stress and material solidity is used And new methods, suitable for solving various material strength tests, calculations and evaluation problems of various material properties.

Description

technical field [0001] The invention relates to an action science method for measuring material properties and a measuring instrument thereof, belonging to the research fields of theoretical mechanics, applied mechanics and experimental mechanics. Background technique [0002] Traditional theoretical mechanics, applied mechanics, and experimental mechanics have a vague understanding of the essential meaning of material properties. Therefore, for a long time, the selection of scale values ​​used to characterize mechanical properties has not been accurate enough. In theoretical mechanics, applied mechanics, and experimental mechanics, the scale values ​​used to characterize the properties of materials are mainly various coefficients and moduli developed according to Hooke's law. These coefficients or moduli are often inaccurate and do not represent an objective meaning of the material properties at all. For more than 200 years, people have always had some misunderstandings ab...

AI Technical Summary

Problems solved by technology

However, the mechanical test equipment is inconvenient to use, and the measured result data often does not have universal significance, poor comparability, is unreliable, and cannot meet the application requirements

Mechanical experiment data cannot be used for scientific prediction such as earthquake disaster prediction, because the parameters obtained from the test results are various moduli, rather than property parameters that reflect the variable or immutable characteristics of materials
