Title:Effects of inelastic action on resistance to various types of loads; inelastic behavior of aluminum alloy I beams with elliptic type web of ductile members made from various classes of metals part 7 section cutouts
Author(s):Worley, Will J.; Breuer, Fred D.
Subject(s):Inelastic Action
Abstract:This report represents a continuation of WADC Technical Report 56-330, Part II, April, 1957 and Part V, May, 1957. This continuation was undertaken to investigate the fully plastic bending behavior of aluminum alloy I-beams with elliptic-type web section cutouts. As in the two earlier reports, the mechanism method of analysis employing the Upper Bound Theorem was used in predicting the ultimate loads of the various beams. The I-beams were loaded as simple beams with center loading. The mathematical relations were developed to enable solution by means of an electronic digital computing machine, the Illiac. The results obtained on the Illiac indicated that a diamond shape web section cutout was the most favorable type for resisting fully plastic bending. Tests were conducted which substantiated the results obtained on the Illiac.
