Tensile experiment of the marker rod.
First, the purpose of the experiment.
The tensile test of the marker rod aims to determine the mechanical properties of the marker rod under the action of tensile force, including its tensile strength, yield strength, elongation and other parameters, so as to provide a scientific basis for the design and use of the marker rod.
Second, the principle of the experiment Bohua sign rod manufacturers This experiment uses the tensile test method to carry out tensile test on the sign rod. During the test, a progressively increasing tensile force is applied to the marker rod until it breaks, and the stress-strain curve during the tensile process is recorded. Through the analysis of the curve, the mechanical properties of the marker rod such as tensile strength, yield strength and elongation can be obtained.
3. Experimental procedures.
1.Preparation of the specimen: Select the marker rod that meets the requirements and cut it into the specified size and shape.
2.Mounting the specimen: Fix the specimen on the tensile testing machine to ensure that it is in good contact with the testing machine grips and that there is no twisting or deflection.
3.Adjust Initial Tension: Apply a certain initial tension to the specimen to eliminate the initial bending or warping of the specimen in the grip.
4.Start tensile test: apply a tensile force to the specimen at a constant velocity, record the deformation of the specimen and the stress-strain curve.
5.Data Recording: During the tensile process, the stress and strain data of each stage are recorded, including yield point, tensile strength and elongation.
6.Result processing: Based on the recorded data, the stress-strain curve is plotted, and the experimental results are analyzed and processed.
7.End of experiment: After data recording and processing, the tensile force is gradually released to return the specimen to its original state.
