National Advisory Committee for Aeronautics, Technical Notes - Handbook of Structural Stability; Part I - Buckling of Flat Plates

This "Handbook of Structural Stability" presents a rather comprehen-
sive review and compilation of theories and experimental data relating to
the buckling and failure of plate elements encountered in the airframe.
Tb rest the anticipated needs of those who would use this review and com-
pilation, it appeared best to adapt a handbook style of presentation.

The material is not intended as a textbook in which the emphasis is often
on the mathematical development of different types of related problems.
Neither is it intended to compete with the familiar aircraft-company
structures manuals which generally present design information, empirical
data, and methods of extending results beyond the scope of the original
report.

This handbook attempts to cover the generally neglected area between
the textbook and the structures manual. no attempt is made to present an
exhaustive coverage of mathematical techniques which are of great impor-
tance in the solution of buckling problems} This material has been well
presented in several excellent books and papers which are included in the
reference list. The subject of columns is comprehensively treated in
several books and, therefore, the inclusion of such material in this
review did not appear to be warranted.

This presentation primarily constitutes a critical review of devel-
opments concerning buckling and failure of plate elements since the
early 19h0' s. This date has been selected since the last comprehensive
review of this nature (ref. I) appeared at that time.

In order to seat the varying nueis of airfrare designers and
analysts, Structures methods, and research engineers, it appears to»:
to organize this handlnok-ns follows: The main text discusses assu:y—
tions, linitutions, and background of the available literature; the
appendix contains a surrary of this material and indicuLus the munnvr
in which this information is to he used in analysis and design. It is
anticipated that, after the material in the rain text has been reviewed,
reference to only the appendix will he made in a nmJority of routine
applications. The duplication in these two main parts has been held to
a minimum consistent with completeness and intelligibility.
