This paper presents the results of two static tests of structures in use on certificated aircraft and a description of finite element models of these structures. Comparisons of the results of the static tests and the predictions of the finite element analyses are given. Problems encountered in the development of the finite element models are presented, and solutions to these problems are discussed. Implementation, applications, and functional aspects of finite element analysis are also discussed. This paper does not cover the basic mathematical development of finite analysis, nor dynamic analysis applications.
