Finite element model of rail and rail slab: (a) model of rail, the distance between two fasteners is 0.6 m, and this length is divided into 20 small units; the total of main DOF nodes is 201. (b) Model of rail slab, continuous elastomer, having an elastic modulus of 3.6e10 Pa, a Poisson’s ratio of 0.1, and a density of 2500 kg/m3, is the solid-45 eight-node-space entity unit. (a) Rail. (b) Rail slab.
