torsion, femoral nail, humeral nail, tibial nail, experiments, plasticity

This article represents a multidisciplinary approach to biomechanics in the field of femoral, humeral and tibial intramedullary nails made of Ti6Al4V or stainless steel. This paper therefore aims to offer our proposed experimental solution (i.e. torsion test) of femoral nails together with their possible assessment. During the solution, the fixation effects were considered in the jaws of a laboratory test machine and elastic and plastic strains (yield limits, maximum torque etc.)
