Description
Summary:Roller burnishing is a very commonly used industrial process. It involves a local plastic deformation on surfaces that permits the fatigue strength of structures to be increased. Crack propagation is indeed delayed by the introduction of compressive residual stresses. In h s way, this process is particularly useful in the presence of stress concentrators like in the fillets of crankshafts or in notched shafts for instance. In the present work, a three-dimensional finite element analysis is carried out with the commercial software ABAQUS in order to model roller burnishng in the fillets of crankshafts. The contact between the workpiece and the tool is simulated and the latter is subjected to a pressure. Thus, all the residual stresses and strains can be calculated after unloading. The outputs are comp
