Bending of Isosceles Right Triangular Plates

Abstract Two methods are presented for the solutions of problems of an isosceles right triangular plate bent by arbitrary transverse loads. One method makes use of a concentrated diagonal load on a square plate. The other uses an antisymmetric load on a square plate. A numerical solution is given for the case of clumped hypotenuse and simply supported legs. A table is given indicating how to solve fifteen of the possible eighteen problems in which an edge is free, clamped, or supported.

Riddle-Type Buckling of Sandwich Columns

The problem of local instability of thick sandwich columns having orthotropic cores is treated under two different types of loading: (a) axial compressive loads acting at the edges of face plates and (b) bending moments acting at the ends of the sandwich column. End points of the face plates are assumed to be pinned. The present method is, however, applicable to general end conditions and for arbitrary axial and transverse loading. I t is shown that the deflected shape is neither symmetric nor antisymmetric, but asymmetric. Numerical calculations and curves are made for various types of cores employed in industry. The results are found to be in good agreement with the experimental data.
