Apparatus for Indentation Test Involving Micom and Evaluating Method of Residual Stress using The Same

摘要

The present invention relates to an instrumented indentation tester with a built-in microcomputer and a residual stress measuring method using the same.;An embodiment of the present invention is a driver installed inside the main body of the tester, a slider connected to the axis of the driver, a slider guide for guiding the slider, the indenter in conjunction with the slider, a load sensor for measuring the indentation load, Instrumented indentation tester with a built-in microcomputer comprising a displacement sensor for measuring the indentation depth, a microcomputer connected to the interface with the driver, and a main computer connected to the microcomputer by wire or wireless to calculate the residual stress of the test specimen. to provide.;The present invention provides an instrumented indentation tester and a method of measuring residual stress using the same, which are advantageous for mechanical property evaluation and can be used for nondestructive measurement. It can be applied to a wide range of structures and has the effect of not being affected by the microstructure.;Tester, Micom, Hardness Tester, Instrumentation Indentation Tester
