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…
