Despite some concern as to proper allowance for the effect of size on the fatigue behavior of materials, little definite information along this line is available for the aluminum alloys of major interest in aircraft design. This investigation was initiated to study the influence of size, particularly the notch-size effect, on extruded 75S-T6 aluminum-alloy test specimens under rotating bending.
