Smoothed particle hydrodynamics (SPH) for modeling fluid-structure interactions
Science China Physics, Mechanics & Astronomy, 2019Fluid-structure interaction (FSI) is a class of mechanics-related problems with mutual dependence between the fluid and structure parts and it is observable nearly everywhere, in natural phenomena to many engineering systems. The primary challenges in developing numerical models with conventional grid-based methods are the inherent nonlinearity and ...

Smooth particle hydrodynamics (SPH) modelling of laser cutting
ICALEO 2008: 27th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2008One of the major obstacles in the simulation of laser cutting is the wide span of length scales and the high velocities encountered. Additionally the melt breaks up into a fine spray or shower of droplets when exiting the kerf. Hence the scope for modeling this process with traditional finite volume or finite element methods is limited.

Smooth Particle Hydrodynamics (SPH) for Simulating 2D Elastodynamics Problems
Applied Mechanics and Materials, 2016SPH is a Lagrangian based computational method that can be used for solving fluids and solid mechanics problems. In this work, SPH is utilized to solve the two dimensional Navier’s equation for linear elastodynamics problems. The SPH technique computes the discrete particle properties using a smoothing distribution function, which takes into account ...

Efficient Implementation of Smoothed Particle Hydrodynamics (SPH) with Plane Sweep Algorithm
Communications in Computational Physics, 2016AbstractNeighbour search (NS) is the core of any implementations of smoothed particle hydrodynamics (SPH). In this paper,we present an efficientneighbour search method based on the plane sweep (PW) algorithm withNbeing the number of SPH particles. The resulting method, dubbed the PWNS method, is totally independent of grids (i.e., purely meshfree) and ...

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
