Fluid-Structure Interaction
Solver
: LAMMPS with the USER-SMD package
Method
:
Solids:
Total Lagrangian SPH to eliminate the tensile instability
Anti-hourglass control to reduce zero-energy modes
Fluid: Classical SPH
Material
:
Solids: elastic perfectly plastic
Fluid: inviscid and compressible (Tait equation)
Interaction
: repulsive Hertzian force
