It is found that the wear will be caused on the corners of the square pin during the stress process, but the amount of wear is not large because this test uses unidirectional loading, as shown in Figure 13.
It was found that wear would be caused by the angle of the square pin during the force, but the amount of wear was not large due to the one-way loading used in this test, as shown in Figure 13.
It is found that the wear will be caused on the edges and corners of the square pin in the process of stress, but the wear amount is not large. Because the unidirectional loading is used in this test, see Fig. 13.<br>
