Stiffened Plate

A new 6-noded stiffened triangular plate element for the analysis of stiffened composite plates based on Mindlins deformation plate theory has been developed. The stiffened plate element is a combination of basic triangular element and bar component. The element can accommodate any number of arbitrarily oriented stiffeners and obviates the use of mesh lines along the stiffeners. Free vibration analyses of stiffened laminated plates have been carried out with this element and the results are compared with those published. The finite element results show very good matching with the experimental ones.

Structural Applications

Piezolaminated smart structures are becoming more popular as they can be used as light weight structures to control structural response in various structural applications. Piezoelectric materials have direct and converse piezoelectric effects which can be adequately employed to control the deflection, shape and vibration of the structure. A finite element methodology based on higher order shear deformation theory is developed for free vibration analysis of smart piezolaminated composite plates subjected to combined action of electrical and mechanical loading. To achieve the accurate prediction of the frequencies, a finite 2D isoparametric element for the mechanical displacement field is combined with an electric potential field. Numerical results are presented for free vibration analysis of simply supported piezolaminated composite plate considering different electric condition with varying thickness to span ratio.
