ICCAS 2007, Portsmouth EFFICIENT GENERATION OF CFD-BASED LOADS FOR THE FEM-ANALYSIS OF SHIP STRUCTURES
This paper describes the technology for coupling CFD and FEM computations and for selecting the appropriate design waves. One core component for linking CFD and FEM is a repository for the ship hydrodynamic results (SHR). Another important component is an algorithm which maps CFD pressures to FEM nodal loads where CFD and FEM meshes need not coincide. Both the exchange file and the mapping algo...
متن کاملA Non-Linear 3D FEM to Simulate Un-Bonded Steel Reinforcement Bars under Axial and Bending Loads
This paper presents development of 3D non-linear finite element model to simulate the response and predict the behavior of un-bonded mild steel bars under axial and bending loading. The models were successfully analyzed with the finite element software ANSYS, taking into account the nonlinear material properties of the reinforced mild steel bars. A bending strain relationship is derived based o...
متن کاملCrumb Rubber-concrete Panels under Blast Loads Preprint
To improve the blast resistance of a wall system, it is necessary to enhance its energy absorption capabilities and/or increase its mass. Much research has been performed on improving the ductility, and thus the resistance, of a wall system using elastic materials externally attached to the tension side of a wall. This project investigated the static resistance of wall systems with elastic mate...
متن کاملStress Analysis of Rotating Thick Truncated Conical Shells with Variable Thickness under Mechanical and Thermal Loads
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...
متن کاملBuckling Analysis of Rectangular Functionally Graded Plates with an Elliptic Hole Under Thermal Loads
This paper presents thermal buckling analysis of rectangular functionally graded plates (FG plates) with an eccentrically located elliptic cutout. The plate governing equations derived by the first order shear deformation theory (FSDT) and finite element formulation is developed to analyze the plate behavior subjected to a uniform temperature rise across plate thickness. It is assumed that the ...
