CLASSIC TAYLOR-BAR IMPACT TEST REVISITED USING 3D SPH
This paper presents an investigation of effects of various parameters used in 3D SPH simulation of classical Taylor-bar test. The investigation focuses on density evolution approaches, material strength models, smoothing length adaptation schemes and sensitivity of artificial viscosity constants. Based on the comparisons on the numerical results obtained, some conclusions are made which are useful in future SPH applications to solid impact and penetration problems.
