Elastic-plastic effect study in hypervelocity impact by SPH method
نویسندگان
چکیده
A new distributed parallel SPH programming scheme using AMR (adaptive mesh refinement) background grid is proposed, in which the size of a grid is decided based on maximal smoothed length of local particles. In detonation simulation, computational complexity of the new scheme is better than O(NlgN) which is the best order of magnitude in the previous methods. Several hypervelocity impact problems are simulated using the new SPH scheme with state equations or strength model. The simulation results are discussed comparison to experimental and computed results in other literature.

A High-Velocity Impact Simulation using SPH-Projection Method
In this paper, a new smoothed particle hydrodynamics (SPH) algorithm for simulation of elastic-plastic deformation of solids was proposed. The key point was that materials under highvelocity impact (HVI) behave like fluids. This led to propose a method which was similar to the socalled SPH-projection method, in which the momentum equations are solved as the governing equations. The method consi...

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...

This study deals with the elastic-plastic impact on moderately thick rectangular plate subjected to uniform in-plane compressive loads resting on the Pasternak elastic foundation. The proposed rectangular plates have two opposite edges simply-supported, while all possible combinations of free, simply-supported and clamped boundary conditions are applied to the other two edges. The dimensionless...

The finite element method (FEM) is often used as the conventional method in computational geomechanics. However, dealing with the large deformation and failure is generally a difficult task for FEM since this method is suffered from grid distortions. In order to resolve this problem, the development of smoothed particle hydrodynamics (SPH) to simulate large deformation and failure of geomateria...
