Experimental and finite element fatigue assessment of the spring clip of the SKL-1 railway fastening system

The fastening system that links the rail and the sleeper in railway lines is an element of high responsibility, since its failure may lead to the derailment of the train. This paper combines an experimental approach and a Finite Element model to assess the structural integrity of the spring clip of...
