【Abstract】 Impact test is a widely used method to evaluate the ability of the impact resistance of ceramic materials. A new measurement machine that can measure the impact resistance ability of ceramic materials was developed. This machine executes impact on a sample with a pendulum, records the force data of the impacted sample, and displays the curve of the changing forces by a PC. By taking into account the impacting impulse, the curve of the changing forces, and the max force, it can qualitatively evaluate the impact resistance ability of the ceramic materials. With the field test of this machine, the influence of the composition, shape and size of ceramic materials on the impact resistance can be examined easily and conveniently.更多还原
