THREEDIMENSIONAL TRANSIENT ANALYSIS OF A SINGLE SUBMERGED CYLINDRICAL SHELL

THREEDIMENSIONAL TRANSIENT ANALYSIS OF A SINGLE SUBMERGED CYLINDRICAL SHELL Threedimensional transient analysis of a submerged cylindrical shell is presented. Threedimensional trilinear eightnoded isoparametric fluid element with pressure variable as unknown is coupled to a ninenoded degenerate shell element. Staggered solution scheme is shown to be very effective for this problem. This allows significant flexibility in selecting an explicit or implicit integrator to obtain the solution in an economical way. Threedimensional transient analysis of the coupled shell fluid problem demonstrates that inclusion of bending mode is very important for submerged tube designa factor which has not received attention, since most of the reported results are based on simplified twodimensional plane strain analysis. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Engineering Computations Emerald Publishing

Abstract

Threedimensional transient analysis of a submerged cylindrical shell is presented. Threedimensional trilinear eightnoded isoparametric fluid element with pressure variable as unknown is coupled to a ninenoded degenerate shell element. Staggered solution scheme is shown to be very effective for this problem. This allows significant flexibility in selecting an explicit or implicit integrator to obtain the solution in an economical way. Threedimensional transient analysis of the coupled shell fluid problem demonstrates that inclusion of bending mode is very important for submerged tube designa factor which has not received attention, since most of the reported results are based on simplified twodimensional plane strain analysis.
