Buckling and post buckling analyses of CWR in the lateral plane (TN-TS-34)

In this Report, the problem of lateral buckling of continuously welded rails subjected to temperature rise, is rigorously studied. The formulation considers variations in the thermal compressive force, due to large buckling deflections and nonlinearities in the lateral, the axial and the torsional resistances. On the basis of variational calculus,...
