THE EFFECTS OF INELASTIC ACTION ON THE RESISTANCE TO VARIOUS TYPES OF LOADS OF DUCTILE MEMBERS MADE FROM VARIOUS CLASSES OF METALS Part XI — Photoelastic Analysis of l-Beams with Elliptic-Type Web Cutouts

摘要

This is the final report on the photo elastic study of I-Beams, and covers the period from May 1, 1958 to date.nThe data presented are intended to supplement the data presented in WADC TR 56-330 Part VII under contract No. AF 33(616)-2753. Report VII presented information on the fully plastic strength while the present report discusses the elastic stress distribution in the web section of I-Beams-with various shapes of elliptic-type web cutouts.nThe prediction of the location of the fully plastic hinges using the shear difference method is discussed for one shape of web cutout. The method shows reasonable agreement when compared with available data on the actual aluminum alloy I-Beam.
