Análise de compósitos de madeira laminada colada e vidro/epoxi, utilizando um elemento finito de alta ordem

Abstract

A class of Cº finite element based on the hight order theory is used in the numerical analysis of laminated beams. In order to eliminate the necessity of a shear correction coefficient, this theory incorporates a non-linear variation of the longitudinal displacements through the beam thickness. The element considered is four-noded cubic with seven degrees of freedom per node. A manufacturing methodology of box-beam made of bond laminated wood and glass/epoxi laminaes is also introduced. Numerical solutions are compared with some experimental results, as well as with Elasticity and Timoshenko theory solution.
