Finite Element Analysis of Natural Vibration in Thin Aluminum Sheet
Journal Title: International Journal of engineering Research and Applications - Year 2019, Vol 9, Issue 1
Abstract
Thin aluminum sheet has a lot of applications in automobile industry, aerospace field, shipbuilding and offshore equipment. This thin sheet of aluminum is attractive for its light weight which will safe energy especially in dragging and lifting of airplanes. Natural vibration in such application has a great important and intense, therefore, modal analysis using finite element method is carried out over a thin aluminum sheet of (100 mm ×100 mm× 2 mm). The application of these sheet may have a stress riser. Therefore, the analysis is extended to involve circular holes for or even elliptical ones. The finite element results give a little difference between the natural vibration of un-notch plate and other with circular or elliptical ones, moreover the eigenvalue and mode contours are explained.
