to request the National Research Council's National Materials Advisory Board (NMAB) to identify issues related to the aging of advanced materials and suggest accelerated evaluation approaches and analytical methods to characterize the durability of future aircraft materials and structures throughout their service lives.

Existing methods for accelerated service simulation testing and damage accumulation rules may be inadequate for analyzing complex structures operating in new environments. There has been considerable work associated with the NASA High-Speed Research program and at the aircraft and engine manufacturers to characterize the performance of HSCT-candidate materials under expected service conditions (Bnunner, 1994; Williams and Johnson, 1994~.
