Purpose: The qualification of influence of model repaired car body parts on the value of coefficient of restitution and evaluation of impact energy absorption of model repaired car body parts. Design/methodology/approach: Investigation of plastic strain and coefficient of restitution of new and repaired model car body parts with using impact test machine for different impact energy. Findings: The results of investigations show that the value of coefficient of restitution changes with speed (energy) of impact. Moreover, coefficient of restitution is smaller for repaired model parts than for new parts. This could have influence on passive safety of vehicle. Research limitations/implications: In the investigations aerodynamic resistance, friction in bearing of pendulum, part of impact energy changing to heat and vibrations were disregarded. Moreover, the investigations have been carried out on model of longitudinal. Only one grade of steel has been tested with using one type of welding. Originality/value: The results of investigation show that repair of post-accident car body parts influences on value of coefficient of restitution and in a result on plasticity of car body and level of passive safety of post-accident vehicle.
