Optimal Flexure Fields for Corners
Publication: Journal of the Engineering Mechanics Division
Volume 100, Issue 4
Abstract
The intention of this technical note is to clarify the somewhat confused situation about the problem of optimal flexure fields for simply supported corners. This problem has far-reaching implications in regard to the existence of solutions in the Prager-Shield theory of optimal plastic design. A solution is presented that satisfies the Prager-Shield optimality criteria for simply supported corners which can be obtained if moment and shear concentrations at the corner are permitted. So-called unidirectional solutions which violate the inequality condition for curvatures in the direction of zero principal moments have been shown to be very highly uneconomical.
