Analysis of application efficiency of polymer composite materials (PCM) in the
development of tractors falling-object protective structures with the use of finite element
method and modern systems of engineering analysis (CAE) is done. An elasticity and fracture
model of composite materials is developed. A series of virtual crash tests of the tractor cab is
carried for both cases with and without PCM. On the basis of this research, a methodology of
designing PCM roofs for tractor cabs is developed.
Keywords: composite material, crash test, design, finite element model, tractor cab.
