“…This would be extremely difficult to achieve with such visual failure criterion. Spiteri et al [7] conducted resonant bending fatigue tests with rolled ductile cast iron crankshaft sections. They come to the conclusion that an accelerating shift of natural frequency is well associated with two-piece failure and thus is an effective failure criterion in resonance fatigue testing.…”

Pipe strength a b s t r a c tSteel pipes used in the oil and gas industry when subject to corrosion pitting may fail as a result of internal pressure and metal cracking influenced by hydrogen embrittlement. The progressive shape of the crack, including at the instant of failure, is predicted under increasing internal pressure. It is proposed that when hydrogen-assisted cracking (HAC) is involved the shape of the crack front may be estimated from a parallel numerical analyses in the absence of HAC. The theory for this is outlined and an example given.

“…Rolling depth of the fillet surface, experimentally measured by the shadowgraphs taken before and after the fillet rolling, was used as the boundary condition under a deformation-controlled procedure. Spiteri et al [19] assumed that the induced residual stress was greatly affected by the rolling force in the ramping up and down stages. In another word, additional operation in the full load stage was considered not to significantly increase the magnitude, or alter the distribution of the residual stress.…”

Finite element approach toward an advanced understanding of deep rolling induced residual stresses, and an application to railway axles

A full-scale railway axle made of medium strength steel EA4T and adopted for high-speed applications, is deep rolled. The induced residual stresses were experimentally characterized by X-ray diffraction and hole drilling. A realistic finite element model is proposed to overcome some of the existing shortcomings in simulation of deep rolling. Deep rolling coverage is defined, formulated and incorporated into the simulation. The model is validated by the experimental measurements. A parametric study is performed to investigate the effect of rolling force (4-19 kN), rolling feed (0.1-0.7 mm/rev) and roll geometry (1.5-10 mm roll tip radius) on the distribution of residual stresses and the induced hardening. A fatigue crack propagation algorithm is used to analyze the influence of technological parameters on the lifetime of railway axles. Lower feeds, higher loads and thicker rolls, all resulting in higher deep coverage, can result in higher improvement against fatigue crack propagation. However, extremely high coverage can deteriorate the performance of deep rolled components. As a general rule of thumb, adopting deep rolling feed to get a coverage level of 500-900%, while avoiding too high rolling loads and too thin rolls, can induce a suitable compressive residual stress distribution; and effectively prevent/retard fatigue crack propagation
