The physical model of motor vehicle destruction under shock loading for analylis of road traffic accident

Experimentally calculated component of the physical model of motor vehicle destruction under shock loading is considered. The results of the development of methods for determining deformation energy of motor vehicles, damaged in road accidents, are presented. Model of studying the processes of motor vehicle deformation and destruction under shock loading conditions is elaborated. Accuracy of deformation energy determination by crash test-based methods is evaluated using experimental- calculation method of hardness. The possibility to determine the speed of motor vehicle motion at the moment of impact with accuracy, sufficient for the practice of carrying out auto-technical expert examination is shown.
