VARIATIONAL FORMULATION OF RAIL OVERTURNING AND A FINITE ELEMENT SOLUTION TECHNIQUE

The equations governing the behavior of the rail system under vertical, lateral and axial loads are set up. The modeling includes the vertical and lateral deformations as well as twisting deformations. The vertical, lateral and torsional stiffness of the ties are modeled by means of springs. In the formulation discrete as well as distributed springs can be included. The stiffness matrix is obtained by a variational method. Following a discussion of the finite element solution techniques a numerical example is given which also uses a direct variational method.
