Simulation of Cold Rolling Process Using Smoothed Particle Hydrodynamics (SPH)
Regarding the reported capabilities and the simplifications of the smoothed particle hydrodynamics (SPH) method, as a mesh-free technique in numerical simulations of the deformation processes, a 2-D approach on cold rolling process was provided. Using and examining SPH on rolling process not only caused some minor developments on SPH techniques but revealed some physical realities. The chosen t...
متن کاملSmoothed Particle Hydrodynamics ( SPH ) : an Overview and Recent Developments
Smoothed particle hydrodynamics (SPH) is a meshfree particle method based on Lagrangian formulation, and has been widely applied to different areas in engineering and science. This paper presents an overview on the SPH method and its recent developments, including (1) the need for meshfree particle methods, and advantages of SPH, (2) approximation schemes of the conventional SPH method and nume...
متن کاملConservative, special-relativistic smoothed particle hydrodynamics
We derive a new special-relativistic version of Smooth Particle Hydrodynamics (SPH) from the Lagrangian of an ideal fluid. The new formulation accounts for the terms that stem from non-constant smoothing lengths, in SPH usually called ”grad-h terms”. To handle shocks a refined artificial viscosity scheme is applied. The performance of this new equation set is explored in a variety of benchmark ...
متن کاملSmoothed Particle Hydrodynamics on GPUs
In this paper, we present a Smoothed Particle Hydrodynamics (SPH) implementation algorithm on GPUs. To compute a force on a particle, neighboring particles have to be searched. However, implementation of a neighboring particle search on GPUs is not straightforward. We developed a method that can search for neighboring particles on GPUs, which enabled us to implement the SPH simulation entirely ...
متن کاملIncompressible smoothed particle hydrodynamics
We present a smoothed particle hydrodynamic model for incompressible fluids. As opposed to solving a pressure Poisson equation in order to get a divergence-free velocity field, here incompressibility is achieved by requiring as a kinematic constraint that the volume of the fluid particles is constant. We use Lagrangian multipliers to enforce this restriction. These Lagrange multipliers play the...
