Residual Life of an Elastic Element of a Spring under the Action of Hydrogen-Mechanical Factors

We propose a method for the evaluation of the residual life of a spring plate of a truck containing a semielliptic crack under the action of cyclic loading and a hydrogen-containing medium. The method is based on the numerical model of fatigue crack propagation. This model is based on the energy cri...

Description
Summary:We propose a method for the evaluation of the residual life of a spring plate of a truck containing a semielliptic crack under the action of cyclic loading and a hydrogen-containing medium. The method is based on the numerical model of fatigue crack propagation. This model is based on the energy criterion of fracture mechanics and takes into account the influence of an external hydrogen-containing medium. We compute the residual lives of hydrogenated and nonhydrogenated materials of the spring plate and compare the results accumulated in these cases.
