Draghopkinson-en Litteraturstudie (Tensile Hopkinson Bar: A Literature Review)
This literature review was written in connection with the work concerning a tensile Hopkinson bar appartus in the project Dynamic Material Properties. Hopkinson bars offer an easy och elegant way of testing materials at high strain rates. A number of different tensile, compressive and torsional Hopkinson bar setups have been researched during the recent years. In this report tensile Hopkinson bars have been studied. The report begins with a short survey of Hopkinson bar theory and then different tensile Hopkinson bar set ups. Important factors concerning tensile testing is length of tensile pulse, raise time, stress level, strain rate and how constant the strain rate is during the test. It is also important to be able to register the test with other means for example high speed cameras and this puts constraints on the design.
