Eikonal decomposition methods for fast computations of beam propagations

Qin Sheng, Shekhar Guha, Leonel Gonzalez

The purpose of this paper is to develop highly efficient decomposition finite difference methods for computing solutions of highly oscillatory beam propagation partial…

An assessment of architecturally appealing, semi-open shock mitigation devices

Rainald Löhner, Joseph Baum

Limitations in space and city planning constraints have led to the search for alternative shock mitigation devices that are architecturally appealing. The purpose of this paper is…

Aluminum alloy profile extrusion simulation using finite volume method on nonorthogonal structured grids

Shumei Lou, Guoqun Zhao, Rui Wang

The paper aims to use the finite volume method widely used in computational fluid dynamics to avoid the serious remeshing and mesh distortion during aluminium profile extrusion…

Design of a laminated composite variable curvature panel under uniaxial compression

Izzet Cagdas, Sarp Adali

The purpose of this paper is to present the optimal design of a simply supported variable curvature laminated angle-ply composite panel under uniaxial compression. The objective…

Estimating the workpiece-backing plate heat transfer coefficient in friction stirwelding

Anders Larsen, Mathias Stolpe, J.H. Hattel

The purpose of this paper is to determine the magnitude and spatial distribution of the heat transfer coefficient between the workpiece and the backing plate in a friction stir…

Numerical simulation of hydrodynamic interaction produced during the overtaking and the head-on encounter process of two ships

D.C. Lo

Based on past studies on the bank effect, the purpose of this paper is to use hydrodynamic principles to simulate the overtaking and the head-on encounter phenomenon of two ships…
