Experimental Investigation of The Effects of Plastic Flow in A tension Panel with a Circular Hole
Year: 1948
Abstract: INTRODUCTION
In structural members, discontinuities such as holes produce stress concentrate ions but the effects of plastic flow on such stress concentrations, especially under repeated loads, are not generally known. Because the localizing of high stresses is believed to be the forerunner of failure under repeated loads (fatigue failure), stress concentrations are considered to be more serious in fatigue than in statics.
The purpose of the present investigation is to determine, for a simple case of stress concentration in a tension panel with a central hole, the effect of plastic flow in modifying the stress concentration factor and the range of stress during 100 loading cycles.
