Abstract : A major goal of the hydraulic ram technology program for aircraft fuel tanks is the development of analytical - numerical tools for the accurate prediction of damage to the tank due to a ballistic projectile. This report discusses the problem of cracking of the tank walls due to hydraulic ram pressures from the penetrating projectile. A bibliography of studies on dynamic crack propagation in transversely deflected thin plates is presented. (Author)
