ASTM D30 and FAA to Sponsor March Workshop on Computational Fracture Mechanics for Composites

The design, analysis and certification of damage-tolerant aircraft composites will be addressed at a March 22-23 workshop sponsored by ASTM Committee D30 on Composite Materials and the Federal Aviation Administration (FAA). Engineers, scientists and software developers interested in learning about future requirements and customer needs will be particularly interested in this one-and-a-half-day program.

The workshop will aid in understanding the difference in durability and damage tolerance testing and analysis for metal and composites structures. Participants will receive up-to-date expert information about the state of the art in this field. Attendees will be able to discuss problems and actively participate in defining a roadmap to certifying these composite structures and identifying software requirements.

The planned schedule for the workshop includes the following.

March 22:
• Opening remarks on Durability and Damage Tolerance Issues for Metals and Composites; A Comparison, by Kevin O’Brien, Army Research Laboratory, Vehicle Technology Directorate at NASA Langley Research Center, Hampton, Va.;
• State of the art in crack growth analysis for metal structures;
• State of the art in fracture analysis for composite structures; and
• Development of analysis tools for damage tolerant aircraft components made of composite materials, including discussion.

March 23:
• Keynote on Damage Tolerance for Composite Structures: A Roadmap for Certification, by Dr. Larry Ilcewicz, FAA, Seattle, Wash.;
• Presentations on critical issues and considerations for applying analysis and tests to predict delamination and debonding; and
• Discussion on defining goals for testing and analysis of damage-tolerant composite structures.

Speakers have been invited from ABAQUS Central, the Army Research Lab/Vehicle Technology Directorate at the NASA Langley Research Center, Bell Helicopter Textron, Boeing Co., Cornell University, ESRD, FAA, Lockheed Martin, NSE Composites, Purdue University, Sikorsky Aircraft and Wright-Patterson Air Force Base.

Interested participants are welcome to stay for the March 23 to 25 meetings of ASTM Committee D30 in Salt Lake City, Utah.
