| Abstract Scope |
Dynamic testing of materials is needed to model high speed forming processes (i.e. hammer forging) and crash/impact behaviour of structures among others. The most common machines to perform medium to high speed tests are the servo-hydraulic high speed tensile machines and the Hopkinson bars. The paper analyses the possibility to use a laboratory forging hammer for the characterization of materials at medium and high strain rates. For this, a forging hammer has been constructed which is accelerated with a pneumatic cylinder and is able to speed up the anvil up to 6 m/s. Cylindrical specimens have been deformed at different speeds and a high speed camera and an accelerometer have been used to monitor the real specimen strain using DIC and the anvil acceleration respectively. The differences when using both sensors information or only the accelerometer are shown and discussed. |
