Performance of the Pressure Testing Machine

　　Tensile test of pressure testing machine: Tensile test (stress-strain test) generally clamps the two ends of the material sample on two fixtures at a certain distance, and the two fixtures separate at a certain speed and stretch the sample. The stress change on the specimen is measured until the specimen fails. Tensile machine Tensile test is one of the most widely used methods to study the mechanical strength of materials, which requires the use of constant speed motion. According to the different load measurement methods, it can be roughly divided into two types: computerized universal tensile testing machine and electronic tensile testing machine.
