Semi-analytical methods for rapid pre-dimensioning of launcher structures subjected to Booster load introduction

This paper describes a new analysis method for orthotropic cylindrical shell structures with arbitrary stiffness distribution. The structural model consists of ring frame elements, orthotropic membrane panels and longitudinal stiffeners (stringer). The element stiffness matrix of the orthotropic pan...
