The Effect of Stringer Width and Damping on the Response of Skin—Stringer Structures

Abstract

Analytical and experimental results for a five-span skin-stringer structure are presented. The analysis uses a transfer matrix technique which considers the effects of stringer dimensions including finite stringer width and damping on the computed forced response. Resonant frequencies, frequency response functions, damping and mode shapes for the first group of modes are compared for theoretical and experimental results. This agreement is found to be good.
