Some Observations on Localized Buckling of Centrally Notched Sheet-Steel Specimens

摘要

Bending strains above a transverse slit in variously sized specimens of constant thickness have been used to indicate the presence of buckling. Buckling was found to occur only in the widest plate tested (48 inches);this is an observation in accordance with present elastic theory. Values of the transverse strains measured at positions ahead of the slit indicate the presence of a stress-relieving mechanism. This may be either a buckling deflection or a localized strain of the Luder-band type.
