Stress Concentrations at HolesFracture Mechanics

 · Stress Concentration Factor (K_t) The 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 Concentration Factor here with the Stress Intensity Factor used in crack analyses.
