SPH by J.-L. Lacome
The examples in this section are from the SPH class of Jean Luc Lacome. Dr. Jean Luc Lacome is employed at LSTC and is the key developer of the SPH (Smooth Particle Hydrodynamics) method of LS-DYNA. You may access the examples separately by the menu on the left. The examples are prepared for LS-DYNA 970 and upwards.
Bar IThis example shows the deformation of two equivalent bars made of plastic material. Initial conditions are specified by *INITIAL_VELOCITY keyword. The upper bar is calculated using Lagrangian discretization, the lower one is calculated using SPH method. |
Bar IIThis example shows the impact of two equivalent bars made of plastic material against a planar rigid wall. The upper bar is calculated using Lagrangian discretization, the lower one is calculated using SPH method. |
Bar IIIThis models the impact of two equivalent bars against a shell structure. The left bar is discretized using Lagrangian solid elements, the right one is discretized using SPH method. |
Bar IVThis is a model of a Taylor bar impacting a rigid wall. The bar is discretized using SPH method. Compare ALE course for solution of the Problem with Lagrangian and Eulerian methods. |
Bar VThis is a model of a Taylor bar impacting a rigid wall. The bar is discretized using SPH method. Compare ALE course for solution of the Problem with Lagrangian and Eulerian methods. |
BirdThis deck shows calculation of the impact of an idealized bird against a turbine blade. The bird is modeled using SPH method, the turbine is discretized using Lagrangian shell elements. Contact is specified with *CONTACT_AUTOMATIC_NODES_TO_SURFACE keyword. |
BootThis is a model of a rubber boot with grease particles covering a rigid rod. The rubber boot and the rod are modeled with solid elements, the grease is discretized using SPH method. |
FoamThis models compression of a foam between a planar rigid wall and a solid block. The foam material is specified with *MAT_LOW_DENSITY_FOAM keyword and discretized using SPH method. |
SieveThis models the impact of a ball against an aluminium sieve. |
