|
Resumo :
|
|
THE PURPOSE OF THIS WORK IS TO PRESENT A SOLUTION OF THE TORSION PROBLEM WITH COMPLEX CROSS SECTION BEAMS BY THE FINITE ELEMENT METHOD. THE ELEMENTS USED ARE HIGH PRECISION HERMITE TYPE, WHICH CAN EXPRESS NULL TRANSVERSE SHEAR STRESS AT THE BOUNDARY OF THE CROSS SECTION AND FURTHER IMPOSE THE CONTINUITY OF THE TRANSVERSE SHEAR STRESS AT THE INTERFACE BETWEEN TWO ISOTROPIC MATERIALS. WE PROPOSE AN ANALYTICAL/NUMERICAL COMPARISON, NUMERICAL/NUMERICAL COMPARISON AND IN THE NUMERICAL/EXPERIMENTAL COMPARISON WE TAKE BEAMS USED CURRENTLY IN BYCICLE WHEELS APPLICATIONS. |
