Experimental and numerical vibration analyses of a stiffened panel (original) (raw)

1993

Abstract

The vibration behavior of a stiffened panel is investigated. The finite element method is employed for the computational analysis. The example structure is modeled using three different approaches. The main difference between the approaches is the way the stiffeners are modeled: as stiffener elements; or as flat shell elements. To estimate the errors, three element meshes on different levels of
