Abstract: This paper presents an explicit formula for the vibration frequencies of simply supported Mindlin plates in terms of the corresponding thin (Kirchhoff) plate frequencies. The formula has been ...

Abstract: This paper is concerned with the plastic buckling of Mindlin plates of polygonal plan shape and whose straight edges are simply supported. The plates are subjected to a uniform in-plane compressive stress. Two well-known ...

Abstract: The Timoshenko beam theory is an extension of the Euler-Bernoulli beam theory to allow for the effect of transverse shear deformation. This more refined beam theory relaxes the normality assumption of plane sections that ...

Abstract: This paper is concerned with the optimal shape of cables subject to external loads only. Design-dependent loads (e.g. selfweight) are assumed to be negligibly small. Consequently, the cable axis is given by the funicular ...

Abstract: The paper investigates the elastic buckling of heavy rotating columns under an axial load using the Rayleigh-Ritz energy approach. Accurate formulas to predict the buckling capacities of the columns are presented. Moreover, ...

Abstract: The optimization of an archgrid consisting of a system of parallel arches running in a number of arbitrary directions is presented. It is established that the archgrid must finish with a single middle surface in the optimal ...

Abstract: When a lateral force acts on a cross‐bracing system, one brace member is subjected to a compressive force while the other is subjected to a tensile force. The tension brace provides a restraint to its compression counterpart ...

Abstract: This study presents a relationship between the buckling loads of sectorial plates based on the Kirchhoff (or classical thin) plate theory and the Mindlin plate theory. Whereas the former plate theory neglects the effect ...
