Smoothed Particle Hydrodynamics (SPH) Method for Stress Wave Propagation Problems
International Journal for Computational Methods in Engineering Science and Mechanics, 2007Smoothed particle hydrodynamics (SPH) method is robust to deal with the problems of impact dynamics. Conventional SPH (CSPH) method converts the kernel integral into a volumetric weighted sum straightforwardly and it is named as particle approximation. This method is very simple and pellucid, but it causes phenomena of tensile instability and numerical

Novel applications of smoothed particle hydrodynamics (SPH) in metal forming
Journal of Materials Processing Technology, 2006Abstract Smoothed particle hydrodynamics (SPH) is a non-mesh based computational method for simulating fluid flows, solid deformation and coupled fluid-structure systems. It is particularly powerful for predicting complex free surface motion and is able to capture fine features in surfaces with little numerical diffusion. The method has been found to

Systems and Control Transactions
This study presents a numerical simulation of the liquid-vapor (L-V) equilibrium stage in a sieve plate distillation column using the Smoothed Particle Hydrodynamics (SPH) method. To simulate the equilibrium stage, periodic temperature boundary conditions were applied.

Applications of Smooth Particle Hydrodynamics (SPH) to astrophysical problems
Computer Physics Communications, 1988Abstract A brief review of astrophysical applications of the Smooth Particle Hydrodynamics method is presented. It is shown that SPH has been applied to a variety of problems usually beyond the capabilities of standard techniques. Two examples, mass exchanging white-dwarf binaries and colliding planets, illustrate that relatively sophisticated ...

Smoothed particle hydrodynamics (SPH) simulation of a tuned liquid damper
Journal of Hydraulic Research, 2010The roll motion response of a single degree of freedom (SDOF) structural system to which a rigid rectangular partially filled liquid tank has been attached is considered. The SDOF structural system with the empty tank is first described with a mathematical model and this model is validated by performing decay experiments as well as experiments in which

An approach for tension instability in smoothed particle hydrodynamics (SPH)
Computers & Structures, 1995Abstract Smoothed particle hydrodynamics (SPH) has the potential to be an important method for structural analysis. However, the SPH method is currently plagued by tension instability. In this work, a new unconventional approach is introduced, in which the stresses are calculated at points other than the SPH nodes, to address this difficulty.

Modelling breakwater roughness with smoothed particle hydrodynamics (SPH)
2010Smoothed particle hydrodynamics (SPH) is used to simulate flows over armoured breakwaters to determine the numerical value of the equivalent surface roughness in the absence of overtopping.

SPH-Net: Hyperspectral Image Super-Resolution via Smoothed Particle Hydrodynamics Modeling
IEEE Transactions on CyberneticsReconstructing a high-resolution hyperspectral image (HSI) from a low-resolution HSI is significant for many applications, such as remote sensing and aerospace. Most deep learning-based HSI super-resolution methods pay more attention to developing novel network structures but rarely study the HSI super-resolution problem from the perspective of image ...
