Fatigue Behavior, Strength, and Failure of Aluminum Foam

Abstract

Foaming processes and the quality of the foamed material have improved considerably during the recent years. It now worth to evaluate the application of aluminum foams for helicopter components to reduce production costs and weight. Since the operating conditions of helicopters expose materials to repeated or fluctuating strains the fatigue behavior of foam materials is of crucial importance for their evaluation as potential materials for helicopter components.
