J.F. Harris and A.R. Robinson (University of Illinois at Urbana), “Numerical methods for the analysis of buckling and postbuckling behavior of arch structures”, a technical report of a research program sponsored by the Office of Naval Research (ONR), Contract No. N 0014-67-A-0305-0010, Project NAVY-A-0305-0010, September 1970
Object and Scope of the Project:
The main objective of this study is to develop a set of numerical methods suitable for investigating the load-deflection and bifurcation characteristics of structures for which significant nonlinear behavior is possible. The methods are applicable to a wide variety of structures, but will be examined in detail only with reference to one of the simplest types of structures possessing the necessary complications in behavior - the planar arch under a concentrated load.
