specific Embodiment approach

[0052] The purpose of the present invention is to quantify the mechanical performance parameters of the test material through the combination of compression deformation experiment and computer aided engineering calculation. As long as there are no restrictions on the selection of materials in the linear elastic range and the initial plastic yield stage of the metal, any self-made standard sample can be selected for testing. The implementation process is not limited to any process of experiment and simulation, but from the mutual Obtaining the real apparent mechanical performance parameters of the material during the calibration process is of great significance for the strength design and reliability analysis of components.

Abstract

The invention relates to a method for estimating material property, and the method comprises the following steps: acquiring the actual transformation displacement of a tested material through a mechanical experiment under a specific working condition; according to a preset property parameter of the tested material, acquiring the simulated transformation displacement of the tested material by utilizing the computer aided engineering to simulate the mechanical experiment under the specific working condition; comparing the simulated transformation displacement with the actual transformation displacement, thereby acquiring the actual property parameter of the tested material; and according to the actual property parameter of the tested material, acquiring the working property of the tested material under various working conditions by utilizing the computer aided engineering to simulate the mechanical experiment under other working conditions. The invention relates to the method for estimating the material property. The system and method for estimating the material property provided by the invention can be used for accurately acquiring the property parameter of the material through experiment and computer aided engineering simulation and performing the simulation test for various working conditions according to the property parameter of the material, thereby avoiding the defect of huge test work load caused by retesting the material property under the condition of the change of the tested working condition.

Description

technical field [0001] The invention relates to the field of material evaluation, more specifically, to a material performance evaluation method and system realized by means of computer-aided simulation. Background technique [0002] Generally, there is a certain difference between the material performance parameters used in actual engineering and the nominal parameters in the standard manual. This is because most engineering materials are composite materials, and the difference in the microscopic components of the material directly determines the macroscopic mechanical properties of the entire material. Performance changes, especially for some casting materials, heat-treated materials and alloy materials, etc., the proportion of internal micro-components is affected by external processes and environmental factors, resulting in significant differences in macro-mechanical properties. With the development trend of high precision in the machine tool industry, modern precision m...
