Plastic Flow of Aluminum Aircraft Sheet Under Combined Loads-II (NA-150)

Abstract

This report describes the results of a study of the effect of specimen size (length and width) on the limiting elongation values in tension and their distribution as a function of gage length for 0.040" Alclad 24-SO sheet. On the basis of these results it is proposed to confine future tests on other grades and tempers to two modified tension specimens and the standard A.S.T.M. sheet specimen. One of the modified tension specimens will be of sufficient length (12") so that the uniform as well as the local elongation may be determined. The other will be a wide specimen with curved edges so designed as to limit lateral contraction to a minimum during stretching in the tension direction.
