| Title: | Elementos finitos isoparamétricos mixtos para flexion de placas |
| Author(s)/Inventor(s): | Gaston Bignon, Pablo |
| Advisor: | Carneiro, Fernando Luis Lobo Barboza |
| Abstract: | Tomando como base el conocido modelo mixto para flexión de placas con desplazamiento transversal y momentos continuos, se desarrollan elementos isoparamétricos para placas homogéneas, según la teoría de Reissner. Son analizados casos particulares de carga variable de superficie, carga linealmente distribuída y cargas concentradas; placas de contornos curvos, moderadamente gruesas y espesor variable. Un tratamiento especial se reserva para placas "sandwich" y también son presentados, sobre dicha teoría dos nuevos modelos y sus respectivas matrices elementales. |
| Abstract: | Isoparametric finite elements are developped from the well known mixed model for plate bending with continuous transversal displacements and moments, according to the theory of Reissner. Special cases of variable surface load, linear distributed load and concentrated loads are analysed. Studies are performed for plates of curved boundaries and for plates with moderately variable finite thickness. A special procedure is reserved for the sandwich plate. Two new models and respective element matrices are presented concerning this problem and the general plare bending problem. |
