Experimental and theoretical study of the models of elastic-plastic elements vehicles manufactured from alloys with shape memory effect. Dynamic tests were carried out in the area of deformation (20-30%), which allowed to achieve optimum energy absorption and return to its original position for subsequent deformation. The model proved highly efficient in terms of the one-dimensional dynamic loading, such full-scale, and allow for the absorption from 55.8 to 97.8% of the inputs, depending on the initial geometrical proportions. Evaluation of the effect of the scale factor in the simulation of elastic-plastic elements on the basis of an alloy with shape memory effect showed the possibility of transferring the results of experimental studies on a real model of the car of the future.
