GEOMETRICALLY SIMILAR ELEMENT METHOD TO CALCULATE THE STRESS CONCENTRATION FACTOR OF NOTCH

Abstract

Abstract: The stress intensity factor of crack can be calculated from the stress concentration factor of corresponding notch when the boundary condition and other geometric conditions are in the same. The more complicate the boundary condition, the more difficulty to calculate the stress concentration factor. The stress intensity factor can be obtained by the transition method of geometrically similar element. The transition method of geometrically similar element for computation the stress concentration factor of notch is proposed and some problems is computed by this method.

Key words: Bending, Geometrically similar element method, Notch, Stress concentration factor, Tension
