Abstract

The fatigue fracture behavior of a high-impact polystyrene is investigated in air and in a series of alcohols. The fatigue data are analyzed using a modified Williams model which gives lower crack tip craze stresses in the liquid environments than in air. The fatigue thresholds are, however, larger in the alcohols due to crack tip blunting. For a given alcohol, the fatigue crack growth rates and crack tip craze stresses are independent of stress ratios and frequencies.
