R. J. Bucci, M. A. James, Alcoa, Inc., Alcoa Center, PA; D. L. Ball, Lockheed Martin Aeronautics Company, Fort Worth, TX
This talk will cover the aggressive pursuit of structural unitization and will present examples. Also, The consequence of residual stress effects in material characterization & design will be discussed in terms of: Deficits of classic FCGA approach
Next generation FCGR testing & analysis
- ACR "master curve" concept (intrinsic material behavior)
- Overview of data reduction / analysis process
- Example - Al Die-Forging
We will address the quantification of residual stresses and will present:
Proposed design FCGA improvements
We will conclude the presentation discussing a holistic modeling vision for residual stress from evolution in metal processing to impact on final part performance.
