The Dynamic Torque Testing Machine can conduct dynamic high and low cycle fatigue tests, program-controlled fatigue tests, as well as static tests under constant rate, constant strain, and constant stress control, and various conventional mechanical performance tests. It can also perform fracture mechanics tests. According to requirements, it can also conduct partial vibration and impact tests. It can also test the fatigue life, crack propagation, fracture toughness performance of materials or components in a wide range, evaluate the safety of actual test pieces, and simulate working conditions. Through the configuration of corresponding accessories and testing software, it can be used for various materials' crack propagation fracture mechanics and other various mechanical tests.
