THE NUMERICAL ANALYSIS OF HUMAN BODY MOVEMENT DURING FALLS AND SPINE RESPONSE IN CONTACT SPORTS

This paper presents modelling process and numerical analysis of human body behaviour during accidents in contact sports and its consequences for human cervical and lumbar spine. The researches contain creation of model which enables human body motion analysis in a situation corresponding to real falls with simultaneous analysis of internal physiological phenomena in human spine. The model of falling man was created using Working Model 2D program and used to numerical analysis of human motion in frontal plane under dynamical loading corresponding to falls in sport

Lower Leg Injury Mechanism Investigation During an IED Blast Under a Vehicle Using an Anatomic Leg Model

Attacks with improvised explosive device (IED) constituted the main threat to, for example, Polish soldiers in Iraq and Afghanistan. Improving safety during transport in an armored vehicle has become an important issue. The main purpose of the presented research is to investigate the mechanism of lower leg injuries during explosion under an armored vehicle. Using a numerical anatomic model of the lower leg, the analysis of the leg position was carried out. In all presented positions, the stress limit of 160 (MPa) was reached, which indicates bone damage. There is a difference in stress distribution in anatomic elements pointing to different injury mechanisms
