Hopkinson Split Bar, Experimental Stress Analysis, Virtual instrument, Impact loadingAbstract
In this work the measurement of strain generated by impact loads is proposed. Some impact tests are listed, from which the Hopkinson Split Pressure Bar (SHPB) is selected. We present the design of the equipment manufactured and used in this work. The materials and equipment needed to carry out the impact test are proposed, as well as how the strain measurement system should be installed. In the test performed, it is identified that the elements of the SHPB are similarly deformed when tested independently. Thus, there is evidence on the feasibility of measuring strain and that the system shown can be improved in future developments for impact load.
