Preliminary Design of Wings. Volume IV. Minimum Weight Design of Composite Structure.

Abstract

Minimum weight design procedures are developed for composite structure fabricated with plies oriented 0, plus or minus 45, and 90 degrees to the longitudinal axis and subjected to an arbitrary biaxial loading. The design technique for stable structure is based upon a generalized ellipsoidal failure model which includes as special cases the classical models for orthotropic and isotropic structural behavior. The strength and interaction parameters are established by a statistical fit of the available experimental data.
