Abstract: Injuries from non-invasive abdominal blunt trauma represent 75% of no visible bleeding traumas. As a step for additional faster and more reliable diagnostic tool, simulation was performed of karate kick, punch, and pinpoint loading on the front, back, right, and left sides of the abdomen for 31-and 50-years old females and a 45-year-old male 2D segmented computed tomography images. The organs' densities and mechanical properties were applied. Mechanical analysis was performed during 0.5 s, 1 s, 1.5 s and 2 s loading time. The results, compatible with previous literature, indicated the affected regions of liver, spleen, pancreas, kidney, and colon by the trauma.

Keywords: liver; blunt abdominal trauma; BAT; simulation; finite element; indirect loading; non-invasive.
