Finite Element Models for the Supportability of United States Air Force Aircraft Structures

Abstract

A study and survey of the use of finite element models of aircraft structures in the Air Force has been conducted. The results show that the Air Force is not getting full value for the resources that are invested in models, both directly and by contractors. Contractors are not required to deliver the models they create to the Air Force. When the Air Force needs these models, they must either be procured from contractors, re-created, or foregone. Models that are available are often documented inadequately, or not at all. A centralized Air Force activity is proposed, in which models are acquired, documented, verified, exercised, modified, publicized, and disseminated. Database software has been identified for use in this Center. Also, a Mil-Standard is proposed that could be used for future model delivery requirements. A Phase II effort is proposed in which the ideas developed in Phase I would be expanded and exercised in anticipation of future permanent establishment of the Center. Keywords: Finite element models; Database; Structural analysis.
