WebbThe Stress Concentration Factor,\(K_t\), is the ratio of maximum stress at a hole, fillet, or notch, (but not a crack) to the remote stress. For our case of a hole in an infinite plate, \(K_t = 3.\) Do not confuse the Stress … WebbEquation (3–48) defined a stressconcentration factor K t (or K ts ), which is used with the nominal stress to obtain the maximum resulting stress due to the irregularity or defect. It turns out that some materials are not fully sensitive to the presence of notches and hence, for these, a reduced value of Kt can be used.
