WebFeb 15, 2015 · Among the employed criteria, the Crossland’s criterion has the best accuracy. Abstract. In this investigation, the effects of torque tightening on the fatigue life of double lap simple bolted and hybrid (bolted/bonded) joints have been studied via experimental and multi-axial fatigue analysis. To do so, two kinds of joints, i.e. simple … WebIn this paper, the assumption that this coefficient can be considered independent from the gear material, geometry, and loading condition was questioned, and through the combination of numerical simulations with a multiaxial fatigue criterion, a method for the calculation of fkorr was proposed.
