A generalized non-hourglass updated Lagrangian formulation for SPH solid dynamics
Shuaihao Zhang, Dong Wu, Sérgio D. N. Lourenço +1
Hourglass modes, characterized by zigzag particle and stress distributions, are a common numerical instability encountered when simulating solid materials with updated Lagrangian s…
Dynamical pressure boundary condition for weakly-compressible smoothed particle hydrodynamics
Shuoguo Zhang, Yu Fan, Dong Wu +2
This paper introduces a novel dynamical pressure boundary condition for weakly-compressible smoothed particle hydrodynamics (WCSPH). Unlike previous methods that rely on indirect a…
A generalized essentially non-hourglass total Lagrangian SPH solid dynamics
Dong Wu, Xiaojing Tang, Shuaihao Zhang +1
In this paper, we tackle a persistent numerical instability within the total Lagrangian smoothed particle hydrodynamics (TLSPH) solid dynamics. Specifically, we address the hourgla…
