Development of Conceptual Solution of Experimental Setting for Controlled Application of Impact Force on the Head Model Using DIC

Abstract

After noting that head and neck injuries are very common in martial arts sports, a growing need for developing helmet materials and models appeared. In addition to the problems that arise in terms of design, there are also problems in terms of developing the material from which the helmets are made. In terms of design, the helmet must interfere as little as possible with the mobility of the head and neck and visibility, while in terms of material development, it is necessary to ensure optimal mechanical properties of the material from which the helmet is made, which is simultaneously the biggest challenge for helmet manufacturers. In the process of developing models and materials of helmets, there was a need for research in which the development of experimental settings will credibly simulate the blows that are exchanged during a sports fight. The aim of this paper is to make an experimental setup to enable testing of helmets from different manufacturers as well as testing of newer generation helmets. This paper presents a conceptual solution of an experimental setup in which impacts are simulated in controlled conditions, taking into account that the impact image applied to the head model is controlled, so that it is possible to simulate different types of impacts while maintaining the same boundary conditions.
