Risk of injury in lumbar spine during explosion of low-mass charge under vehicle

Abstract

The paper presents the analysis of the results of measurements performed on the testing ground at the Military Institute of Armour and Automotive Technology using an explosive detonated under a vehicle. The paper concerns the analysis of an injury risk in the context of significant short-term accelerations caused by explosive charges of various weights. The aim of the analysis was to assess the risk of micro-injuries in soft tissues, induced indirectly by the blast, using a numerical analysis. The measured parameters, such as acceleration and forces generated in the Hybrid III dummy, were assumed as the boundary conditions.
