AB The use of a modern digital image correlation method to investigation of drop tests of two chosen cycling helmets types is described in this contribution. The first type - Arcore T-16 represents the helmets with more rounded uncomplicated surface and the second one - Longus Entry has flatter but more complicated contour. The investigation was directed to determination of helmets deformation and strain fields during their impact to a barrier. A high-speed system Q-450 Dantec Dynamics with cameras SpeedSense9070 Phantom was used to shoot this short time interval.
