What are the experimental steps of the all-aulian puller doing material bending tests? The bending test using a puller is a common material mechanics test method used to assess deformation and destruction of the material under the bending force. And the next thing you know, you're gonna get a little bit of a puzzle from the chinese star。
A bend test to determine the mechanical properties of the material when bearing a bend load. Samples are placed on the lower feeder, the upper feeder loads the sample with a bend load, and tests the relationship between the pressure on the sample and the curved shape of the sample, yielding indicators such as bend strength, curved modulation, breakpoint scratch. They are divided into three-point bends, four-point bends, multi-point bends, bends of the arms and special bends. The bend load test is one of the types of test loads that frequently occur in material tests and is therefore an important consideration when testing a variety of materials。
Specifically, the following steps were taken to carry out the bending test:
First, preparatory work is carried out to ensure the normal working condition of the pull and bending clamps, to check the functioning of the pull test and the reliability of the speed conversion, and to select the appropriate bending clamp. Samples are prepared, which are to undergo a bending test and are placed in a bending clamp, with a switch to a frame, a bending head and a sample pad to ensure that the sample is in good contact with the clamp. In carrying out the preparatory work, do not forget to set parameters and set parameters such as the convulsive velocity of the puller, loading and duration of the test, as required by the test。
Then we start the experiment, start the puller, start bending. The puller will bend the sample at a set rate and record the corresponding bending and bending data. Start the experiment and record the following load values:
1) breaking material before or at specified scratches, recording the fracture bend load; maximum load when maximum load occurs。
2) materials that do not break when they reach the specified scratching level, and records the bend load values when they do。
3) where special requirements exist, the curved load value in excess of the required scratch can be measured as required, and the convulsive strength obtained is referred to as the apparent bend strength。
When the test reaches the established end condition, stop the puller and record the final bending and deformation data. Based on the test data, the corresponding data analysis and results were processed to arrive at the conclusion of the bending test and the associated parameters。
It is necessary to build a hard product and test materials using a tractor. In the following articles, we will also share with you other experiments that can be done by a puller, and the chinese starfleet editor is here to thank you for your attention。
