1results about How to "Convenient Bauschinger Effect" patented technology

The invention relates to the technical field of titanium alloys, in particular to a medium-high strength titanium alloy cyclic loading test method which comprises the following steps of: a, processing a required initial sample; b, placing the initial sample on a material testing machine for a compression loading test, displaying a load-displacement curve on matched software on the material testing machine, and converting the load-displacement curve into a stress-strain curve by a conversion formula; c, machining the compressed initial sample to obtain a tensile test piece; d, carrying out a tensile test on the obtained tensile test piece, and obtaining a stress-strain curve under the loading condition when a preset dependent variable is reached; and e, if the cyclic loading test needs to be further carried out, machining a compressed sample from the tensile test piece, continuing to carry out a compression test, and repeating the step c and the step d to finally achieve the needed cyclic loading test quantity. Accurate cyclic loading test data can be obtained by digital image related equipment, and the Bauschinger effect of a material can be conveniently researched.
