Figure 7 illustrates the stress concentration factor for path 1, and the Mises stress concentration factor is approximately flat in the middle and increases or decreases close to the edges in the softer and harder components, respectively.
Furthermore, it is evident that the radius of agreement and the stress concentration factor have an inversely proportional relation, but said effect occurs faster in plates of this type subjected to flexing; the axial load requires higher radius increases to diminish in equal proportion the magnitude of K.
Using the stress distributions obtained through the MEF, the stress concentration factor was determined in the elastic regime.
(2) the stress concentration factor will be equal to [[alpha].sub.[sigma]] =74.9/51.1 = 1.47 , but with reducing thickness up to [t.sub.w] =2 mm (Fig.
We also consider the plates with holes and calculate the stress concentration factor around the hole.
The stress concentration factor for flexural loading, [sigma].sub.b], for each of the porosities and pore diameters is then calculated by the relation [[sigma].sub.b] = [[sigma].sub.b,porous]/[[sigma].sub.b,solid], where [[sigma].sub.b,solid] is the corresponding observed maximum von Mises stress at the mid-span for the fully dense solid beam model.
The volume fractions of PC used were 1.5%, 3.0%, 4.5%, 6.0%, and 7.5%, while the stress concentration factor K was set to be 1.0 [11].
and Stress Concentration Factor: Kc = (1.2 + 1.3 [S.sub.fn]/[h.sub.fa] ([S.sub.fn]/2 x [r.sub.cs] 1/(1.2 + 2.3 ([h.sub.fa/[S.sub.fn])) (16)
Fatigue strengths of the joints are derived using conventional, material S-N data and the joint stress concentration factor. The role of fretting wear is also discussed.
The most dangerous stress concentration factor with "variable success" is available in the areas mentioned.
The model showed the stress concentration factor at the notch to be at least 2.
