ABSTRCT Prediction of the vibro-acoustic responses of fluid-loaded cylindrical shells is important for underwater vehicles. In this work, a number of analytical and numerical approaches to predict the radiated sound power of a fluid-loaded cylindrical shell are compared. In the first approach, an analytical methodology is used whereby the equations of motion for the cylindrical shell are solved...

In this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. Given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (FSDT). These equations are so...

Currently, lattice composite structures have many applications in aerospace industries. The present research analyzed the effect of an external skin consisting of a lattice’s cylindrical shell on the buckling strength of composite materials, both numerically and experimentally. Two classes of specimens, with and without external skins, were fabricated using the filament winding process. To find...

BACKGROUND A common clinical scenario encountered by an orthopaedic surgeon is a patient with a secure cementless acetabular shell and a failed polyethylene liner. One treatment option is to cement a new liner into the fixed shell. The purpose of this study was to evaluate technical variables to improve the mechanical strength of such cemented liner constructs. METHODS The contributions of sh...
