ANALYSIS OF SIZE EFFECT FOR NOTCHED MINI SPECIMENS MADE OF STAINLESS STEEL

Abstract eng:
The use of test results obtained on mini specimens requires that the size effect is taken into consideration. The impact of object size on strength properties is interpreted depending on the test conditions. In this paper, a geometrical size effect resulting from the non-linear distribution of stress occurring in the notched specimen was analysed. Two specimens of different sizes were prepared of 1.4301 stainless steel. The finite elements method was used for calculating theoretical stress concentration factor. The impact of size effect was evaluated based on the test results obtained for high-cycle fatigue strength.
