Appendix 1: if needed11. Appendix 2: if needed1.SummaryIn this experiment, we performed an impact test on 2 different specimens (ductile and brittle) to determine the impact resistance for each specimen. Impact tests are made on materials, particularly metals, because it is recognized that the resistance of some materials to shock is 1
dependent upon factors other than those which control its resistance to a steady or slowly applied load. One form of impact test consists of simply dropping a weight on a specimen from successively increasing heights until the specimen fails. The impact or energy load causing failure is taken as the weight multiplied by the height of final drop as the measure of impact strength. In making an impact test, the load may be applied in flexure, tension, compression, or torsion. Flexural loading is the most common; compressive, tension, and torsional loadings are used only in special instances.To perform this experiment, we used Tinius-Olsen Impact Machine.
