Abstract

The invention provides a manufacturing method of a material tensile sample. The method comprises steps that: A, according to the dimension of a standard tensile sample, a punching die of a punching machine is manufactured, wherein the gauge length section width of the punching die is larger than that of the standard tensile sample; B, according to the quality and the thickness of a material requiring punching, a punching machine with a corresponding tonnage is selected; with the punching by using the punching machine and the punching die, a crude sample is obtained; C, the crude sample obtained through punching is subject to finish machining in a numerical control milling machine, such that a standard sample is obtained. The method provided by the invention is advantaged in that: with the method, a thin material standard sample for mechanical property testing can be manufactured with high speed and high efficiency; with the method, numerical control milling machine processing of a plurality of thin materials can be simultaneously carried out, such that processing speed is improved; with the method, the precision of the obtained standard sample is high, and the accuracy of testing results can be ensured.

Description

technical field [0001] The invention relates to the technical field of testing mechanical properties of materials, in particular to a method for making a thin material tensile sample. [0002] Background technique [0003] Tensile test is one of the most common test methods in the testing of mechanical properties of materials. The elastic deformation, plastic deformation, fracture and other stages in the test truly reflect the whole process of the material resisting the external force. The basic mechanical properties of materials can be obtained through tensile tests, such as elastic modulus, Poisson's ratio, yield strength, prescribed non-proportional elongation strength, tensile strength, elongation after fracture, reduction of area, strain hardening exponent and plastic strain than wait. [0004] The bending test is mainly used to test the performance of the material under the action of bending load. It is suitable for determining the strength index of brittle and low ...
