Effect of Stiffeners Position on Vibration Analysis of Plates

Abstract

This paper presents the effect of position of stiffeners on the free vibration analysis of stiffened isotropic plate using Finite Element Method. In this paper, comparative study of stiffened isotropic plate has been carried out. The effect of stiffeners location, different boundary conditions, stiffener thickness to plate thickness and aspect ratios on the vibration analysis of plate has been studied. The vibration analysis of stiffened plate has been studied using Block-Lanczos algorithm. The element selected from the ANSYS software is SOLID186, 20 node solid elements. The results have been compared with the available published results
