Abstract
Since the beginning of mass production, vehicle safety has been the focus of constant study and development, especially in recent decades, with the development of materials, manufacturing processes and associated technologies. Particularly as regard heavy vehicles in agriculture, mining and civil construction, the need to increase the safety conditions of operators has forced the protection structures against high impact loads to evolve from nonexistence to the recent view of compulsion. In this paper, it is introduced a theoretical study on the plasticity phenomenon in metals, a computational analysis of the kinetic energy dissipation and the plastic deformation of metallic plates under high impacts, in order to simulate the conditions of the use of a FOPS (Falling Object Protection System) structure, and an experimental analysis of the deformation and energy behavior of the impact of a body on a metal sheet (drop-test), considering the established in standards. This paper was carried out for the elaboration of an Undergraduate Thesis. Thus, this article represents a reduced version of the complete work, which can be consulted in the online repository of the University of Brasilia.
