Finite Element Analysis of Fluid-Structure Interaction in Pressurized Tank Cars Subjected To Dynamic Impact Loading

This paper presents a computational study of the fluid-structure interaction (FSI) mechanism in pressurized commodity tank cars in railroad application. Within the Lagrangian framework of Abaqus/Explicit, finite element analysis (FEA) is conducted to predict the structural response of tank cars under dynamic impact loading. A three-phase approach is adopted that explicitly models pressurized ga...

Harmonic Response of Pile Groups to Dynamic Loading

A completely general method of analysis for three-dimensional raked piles under harmonic excitation is discussed. The piles have been represented by a three-dimensional frame structure and the soil has been represented by a boundary element discretization scheme. A computer program has been written which carries out this analysis and produces a group stiffness matrix that can be included as a f...

Dynamic Response of a Composite Propeller Blade Subjected to Shock and Bubble Pressure Loading

The interaction between an underwater explosion and a composite propeller involves several physical phenomena that an accurate numerical simulation needs to capture. These include proper description of the initial explosion shock wave, of its propagation in the water, and of its interaction with the propeller blades and any other neighboring boundaries. In this work, a numerical procedure which...
