TL;DR: In this paper, a progressive damage fatigue simulator for variable amplitude loads named FADAS is discussed, which performs ply by ply stress analysis using classical lamination theory and implements adequate stiffness discount tactics based on the failure criterion of Puck, to model the degradation caused by failure events in ply level.

TL;DR: In this paper, the use of the theory of critical distances (TCD) was extended to notched components subjected to torsional fatigue loading, and two different hypotheses were proposed: (i) that the critical distance under torsion is the same as that under uniaxial fatigue loading; (ii) that a crack subjected to cyclic shear stress is determined by the non-propagation of Mode I branched cracks.

TL;DR: In this article, a framework of fatigue reliability assessment for existing bridges in lifetime serviceability considering the random effects of vehicle speed and road-roughness condition is presented, and the revised equivalent stress-range is introduced to include fatigue damage accumulations for one truck passage.
Abstract: During the life cycle of a bridge, dynamic impacts due to random traffic loads and deteriorated road surface conditions can induce serious fatigue issues for bridge components. It is necessary, and more realistic than the deterministic approach, to use reliability methods and treat the input parameters as random variables for the vehicle-bridge dynamic system. This paper presents a framework of fatigue reliability assessment for existing bridges in lifetime serviceability considering the random effects of vehicle speed and road-roughness condition. Since each truck passage might generate multiple stress ranges, revised equivalent stress-range is introduced to include fatigue damage accumulations for one truck passage. Therefore, the two variables, i.e., the stress-range numbers and equivalent stress ranges per truck passage, are coalesced in the newly defined variable based on equivalent fatigue damage. The revised equivalent stress-range is obtained through a fully-computerized approach toward so...

TL;DR: In this paper, a 3D nonlinear stress analysis model has been applied to estimate stress fields of the railway mono-block wheel in heat treatment process, and the model was then used to calculate stress intensity factors and fatigue life of railway wheel.

TL;DR: In this paper, a premature failure that occurs prior to the expected load cycles during the vertical fatigue tests of a rear axle housing prototype is studied, which mainly originated from the same region on test samples.
