AFFDL-TR-69-42, STRESS ANALYSIS MANUAL (AUG-1969)
AFFDL-TR-69-42, STRESS ANALYSIS MANUAL (AUG-1969)., This analysis manual is issued to provide a general purpose structural analysis
capability and to serve as a source of data. It represents a collection of techniques
from a wide variety of industry sources, textbooks, periodicals, and government
agencies. Attempts have been made where applicable to give appropriate recognition
to each source. If any omissions or corrections are noted please contact Mr. Gene E.
Maddux, AFFDL(FDTR) Wright-Patterson AFB, Ohio 45433. This preliminary issue of the
manual will be followed by periodical updates which will be distributed to the
original requestors. -
Based on the evaluation of the stress analysis and design techniques and procedures
collected from numerous sources, this stress analysis manual covers the principal
structural elements of aircraft construction. The manual proper consists of eleven
chapters devoted to the stress analysis of beams, columns, bars, trusses, frames and
rings, plates, membranes, pressure vessels, lugs, shafts, and bearing surfaces. To
make the manual as functional as possible, the analysis methods presented are straightforward,
and detailed derivations of equations and methods .are purposefully omitted;
still, such derivations may be obtained from the references listed in the Introduction.
Sample problems are liberally interspersed to illustrate the analysis methods, and
much design data are presented in the form of nomograms and tables to aid computations.
To anticipate updating and improvement of the manual, the methods presented follow
current design and analysis practices. The development of the manual also sought to
anticipate the introduction of machine methods for stress design when procedures become
sufficiently standardized. To facilitate the use of the manual, a comprehensive keyword index includes all significant words of the section headin•s of each chapter.
