Development of an impactor for the Taylor anvil test
 Müller, Samuel ; Forejt, Milan (oponent) ; Jopek, Miroslav (vedoucí práce)
The Master Thesis describes the differences between quasi-static and dynamic material tests and discusses the effect of strain rate in forming processes. It contains a detailed description of Split Hopkinson pressure bar test, Split Hopkinson tensile bar test and Taylor anvil test. The thesis contains a basic theory of ballistics and the history of the development of the material sample carrier for the Taylor test and the analysis of its current state. A new sample carrier was developed for the adjusted diameter of the Taylor test equipment. The shape of the carrier was designed, based on simulations in ANSYS software and practical testing. The carrier was made by 3D printing technology, FDM method. Samples of aluminum alloy 2024-T3 were tested using the new samples carriers. Dynamic flow stress was determined, and the strain rate constant was optimized for specifics impact velocities.
