WebThe Dang Van criterion is classified as a ‘micro-structural’ method because it considers stresses and crack initiation at the local level. Unlike other methods, output from the analysis is always expressed as a safety factor as opposed to fatigue life. Fig. 2 : Mesh and loads applied to the engine cradle Webσ0/σ−1 according to the Findley fatigue criterion. 6.2.2 Dang Van’s model Dang Van’s criterion [2, 3] is based on a two-scale approach. In metals the fatigue crack initiates at …

Multiaxial Fatigue Fatigue Life Prediction

WebThis paper includes comparison of the results for constant amplitude loading with a non-zero mean value and for random loading with zero or non-zero mean values. It has been shown that for 10HNAP steel the algorithm of fatigue life calculations using the Dang Van criterion gives satisfactory results. WebSep 27, 2024 · An iteration of the Dang Van criterion is presented that focuses exclusively on surface-parallel material planes, yielding a standardizable approach for the study of tooth flank fracture in spiral bevel gears. It is shown that Dang Van’s shear stress amplitude and maximum hydrostatic stress along a surface-perpendicular path can adequately be ...
