WebbThe mechanism of stress and strain concentration at fatigue loading is governed by two fundamental effects. Within the yield range of ductile materials the macro-support effect … Webb2.26. In-field use of the TCD to estimate lifetime of notched components in the medium-cycle fatigue regime. The linear-elastic stress field close to the notch tip ( Fig. 2.26b) can now be used to calculate the maximum principal stress range, Δσ 1, a, at a distance from the notch tip equal to LM ( Nf, a )/2.

Webb1 mars 2002 · In particular, the in-plane theoretical stress concentration factors for short rectangular plates with centered circular holes subjected to uniform tension are … WebbThe stress concentration factor should not be confused with the stress intensity factor, which is used to define the effect of a crack on the stresses in the region around a crack tip. [2] For ductile materials, large loads can cause localised plastic deformation or yielding that will typically occur first at a stress concentration allowing a redistribution of stress … WebbThere are experimental methods for measuring stress concentration factor including photoelastic stress analysis, brittle coatings or strain gauges.
