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…
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…
Essentially non-hourglass and non-tensile-instability SPH elastic dynamics
Shuaihao Zhang, Sérgio D. N. Lourenço, Dong Wu +2
Since the tension instability was discovered in updated Lagrangian smoothed particle hydrodynamics (ULSPH) at the end of the 20th century, researchers have made considerable effort…
