HIGH VELOCITY IMPACTS SIMULATIONS WITH SPH METHODS IN LS-DYNA
Several high velocity impacts (HVI) can be simulated using the SPH method in LS-DYNA Space debris whose quantity is on the rise now pose a major threat to satellites Effective impact models enable both the development of more efficient protections and the prediction of the damage that an individual HVI will cause to structures |
What is high velocity impact on laminated composite panels?
High velocity impact on laminated composite panels isinvestigated by modeling, simulation, and experiments. Impact velocities of 100, 200, and 300 m/s are considered and normal as well as oblique impacts are studied.
How is high/hyper velocity impact with extreme deformation modeled?
In the existing modeling of high/hyper velocity impact with extreme deformation including the above-mentioned models, the failure in material is normally controlled by the EoS, the plasticity model, and the damage model. When the material reaches the critical state, how it behaves under damage is decided by the damage model.
What is a high velocity impact test?
The samples are subjected to a high velocity impact with impact velocities ranging from100 m/s to 300 m/s where impact scenarios perpendicular and oblique to the impacted surface are considered. The impact tests are carried out at the DLR Stuttgart using their in-house gas gun setup.
What is a normal impact velocity?
Impact velocities of 100, 200, and300 m/s are considered and normal as well as oblique impacts are studied. FEM simulations are conducted to design three different laminate configurations to achieve the cases of a reflecting, almost stucking, and fully perforating impactor, respectively.
