NUMERICAL ANALYSIS OF SEAWALL OVERTOPPING PHENOMENON BY PARTICLE METHOD

Numerical Analysis of Composite Beams under Impact by a Rigid Particle

Analysis of a laminated composite beam under impact by a rigid particle is investigated. The importance of this project is to simulate the impact of objects on small scale aerial structures. The stresses are considered uni- axial bending with no torsion loading. The first order shear deformation theory is used to simulate the beam. After obtaining kinematic and potential energy for a laminated ...

Numerical Simulation of Squeezed Flow of a Viscoplastic Material by a Three-step Smoothed Particle Hydrodynamics Method

In the current work, the mesh free Smoothed Particle Hydrodynamics (SPH) method, was employed to numerically investigate the transient flow of a viscoplastic material. Using this method, large deformation of the sample and its free surface boundary were captured without the cumbersome process of the grid generation. This three-step SPH scheme employs an explicit predictor-corrector technique an...

Numerical Simulation of Wave Overtopping Over Composite Berm Breakwater

Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on  a laboratory model conducted by Losada et al, cali...

The Application of Numerical Analysis Techniques to Pattern Recognition of Helicopters by Area Method

In this paper, a new method to selecting different viewing angles feature vector is introduced to recognition different types of Helicopters. Feature vector 32 components based on characteristics of the shape, Area and a length to describe a binary two-dimensional image was created, shape feature and length feature not only effective but area features effective and were used. New features vecto...
