Cast Aluminum Structures Technology (CAST) Structural Test and Evaluation (Phase V). Part II. Fatigue and Fracture Properties of Cast Aluminum Bulkheads

摘要

The fatigue and fracture properties of four cast A357-T6 aluminum alloy bulkheads were investigated. Constant amplitude fatigue, crack growth, and fracture-toughness specimens were excised from the bulkheads for this purpose. The data obtained from these specimens confirmed the assumed properties used in the durability and damage tolerance analyses of the bulkhead.
