Instrumentation oscillograph impact tester

This equipment is primarily designed for impact resistance testing of various metal and non-metallic pipes, plates (including non-metallic materials such as plastics, ceramics, nylon, and building materials).  Utilizing an impact force sensor and testing system, the high-speed data acquisition card measures load and deformation transient values during the fracture process of impacted specimens through oscillographic impact sensors. It captures the force-displacement-energy curve of the impact process along with characteristic points on the curve: yield force Fgy, maximum force Fm, crack initiation force Fiu, crack propagation termination force Fa, maximum force energy Wm, crack initiation energy Wiu, crack termination energy Wa, total impact energy Wt, and corresponding displacements. This enables comprehensive analysis of specimen fracture patterns, demonstrating material's dynamic impact load resistance, stress-deformation characteristics under impact, and dynamic fracture toughness at high strain rates. 

Impact resistance stands as a crucial research focus in materials science, playing a vital role in determining the safety and reliability of materials or products.  When developing new materials, experts must evaluate their ability to withstand impact energy throughout service life and assess fracture behavior during failure, enabling precise identification of material vulnerabilities to foster the creation of more competitive materials.  Engineers applying these materials can enhance engineering safety by accurately understanding their impact resistance characteristics, selecting optimal materials with the best impact performance, thereby improving product quality while reducing costs.
