tailieunhanh - Free vibration analysis of isotropic plate with stiffeners using finite element method

This paper presents the free vibration analysis of stiffened isotropic plate by means of finite element method. Stiffeners are used in plates to increase the strength and stiffness. The effect of position of stiffeners on isotropic plate has been studied which involve the possible combination of clamped and free edge condition. | Free vibration analysis of isotropic plate with stiffeners using finite element method Engineering Solid Mechanics 3 2015 167-176 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Free vibration analysis of isotropic plate with stiffeners using finite element method Devesh Pratap Singh Yadav Avadesh K Sharma and Vaibhav Shivhare Department of Mechanical Engineering Madhav Institute of Technology and Science Gwalior India ARTICLE INFO ABSTRACT Article history This paper presents the free vibration analysis of stiffened isotropic plate by means of finite Received 6 January 2015 element method. Stiffeners are used in plates to increase the strength and stiffness. The effect Accepted 5 May 2015 of position of stiffeners on isotropic plate has been studied which involve the possible Available online combination of clamped and free edge condition. The model has been discretized using a 20- 6 May 2015 Keywords node solid element SOLID186 from the ANSYS element library. The natural frequencies are Stiffened plate calculated using Block-Lanczos algorithm. The comparisons of stiffened plate with the Stiffeners available results are found to be in good uniformity. The effect of different boundary Finite element method conditions stiffeners location thickness ratio stiffener thickness to plate thickness and aspect Free vibration ratio on the vibration analysis of stiffened plates has been studied. 2015 Growing Science Ltd. All rights reserved. 1. Introduction Stiffened plate improves the strength to weight ratio and makes the structure cost efficient. Stiffened plates have been widely used in many industrial structures such as aerospace structures decks and aircraft structures etc. Barton 1951 studied the free vibration problem of skew cantilever plate. Dawe 1966 employed the Parallelogram elements for rhombic cantilever plate problems. Leissa 1973 attempts to present comprehensive and accurate analytical results for .
