USING FINITE ELEMENTMETHOD TO DETERMIN EIGENFREQUENCIESOF TWO L-SHAPED PLATENSASSEMBLYEMBEDDED ON A SURFACE. PART II

Abstract

This study proposes a method for locating and evaluating plate damage based on the determination of natural frequencies and modal forms of defective plates using an optimization approach. For simulations finite element method is used, form SolidWorks software. The efficiency of the presented method is explored by a comparison of the results obtained for several case studies of L-shaped plates assemblies having different defects and positions on plates. The results obtained confirm the applicability and effectiveness of the suggested method for solving the problems of localizing and quantifying defects on plates.
