In this study, a dynamic momentum trapping mechanism that is simple to assemble and configure was constructed and affixed to a conventional Split Hopkinson Pressure Bar (SHPB) system.

Abstract

In dynamic applications, the effective use of kenaf composite materials necessitates comprehensive and precise elucidation of their mechanical response under high strain rate loading conditions. Accurately measuring the sample’s deformation can only be achieved using a pulse-trapping technique. In this study, a dynamic momentum trapping mechanism that is simple to assemble and configure was constructed and affixed to a conventional Split Hopkinson Pressure Bar (SHPB) system. The effectiveness of the verified momentum trap approach was shown when the secondary wave of compression was decreased by 50 percent in the application of momentum trapping that stopped the specimen from coming in contact with the incident bar, resulting in a much-improved correlation between various strain rates and the failure of kenaf composite microstructure.
