Resonance analysis of hybrid stiffened plate with finite element analysis

Abstract

Longitudinally compressed stiffened plates can be investigated using a variety of methods. Finite element analysis (FEA) is an efficient method, also used to analyze the dynamic behavior of structures. The dynamic behavior of the hybrid stiffened plate can be further investigated by modal analysis. The analysis can be used to perform the resonance calculations required for plate applications. In the hybrid plate test, the Young's modulus of the base plate and the stiffeners are different, assuming that they are made of different materials.
