An Evaluation of the Service Failure of Aluminum Nose Cones Using Four Test Techniques.
Abstract
Service failure of 7075-T6 aluminum nose cones was evaluated by four techniques: 1. Residual stress measurements (hole drilling technique). 2. Notched crack initiation toughness tests. 3. Verification of fracture toughness. 4. Simulation tests of finished nose cones. In this examination, residual stress differences contributed most to the failure analysis. Keywords: Residual stresses, simulation, ultrasonic tests.
