ON THE FRICTIONAL BEHAVIOR OF THERMALLY LOADED BEAMS RESTING ON A PLANE

The problem of an elastic beam resting on a frictional surface and loa ded by a uniform temperature moment is treated analytically and numeri cally. The introduction of proper non-dimensional parameters identifie s the deformation pattern which varies with monotonically increasing t emperature load in a self-similar manner. This fact reduces the comple xity of the mathematical system considerably and offers the derivation of the solution on an analytical basis. Several approaches are descri bed, discussed and compared against each other. This problem is typica l for a broader class of problems involving Coulomb friction in beam d eformation. In addition to the fact that it is interesting from the st ructural as well as from the mathematical points of view, it is of pra ctical importance, for example in the simulation of the cooling proces ses of hot rolled railway rails.
