Impact and high velocity impact analysis

Virtual Performance Solution features major enhancements for the analysis of high velocity impact scenarios. With Virtual Performance Solution, you can analyze the dynamic behavior of materials or products under high speed impact using our dedicated application PAM-SHOCK.

Besides, the simultaneous use of explicit and implicit modules within Virtual Performance Solution is very welcomed by the Aerospace & Aeronautics industries for advanced structural dynamics and impact simulations. Simplifying the processes, it helps marking another step towards a leaner innovative enterprise.

 

Aerospace

Validated with the European Space Agency against experimental data for hypervelocity impacts, PAM-SHOCK supports the following simulation needs in the aerospace industry:

  • Space Debris Shielding
    One of the most advanced capabilities of PAM-SHOCK concerns the response of matter under extreme strain rates and pressures. Under these conditions powerful shock waves appear in the condensed associated media which lead to incipient melting and vaporization phenomena.
    PAM-SHOCK offers a range of suitable material models and equations of state that describe the full range of the above thermodynamic processes. Furthermore, in order to strengthen an effective protection of the satellites and space modules against arbitrary impacts with orbiting Space Debris, the advanced Smoothed Particle Hydrodynamics (SPH) option allows simulation of oblique impacts upon Whipple and Double Bumper metallic and non-metallic spacecraft shields.
  • Spacecraft Pyrotechnic Separation
    PAM-SHOCK offers a range of suitable material models and equations of state that describe the full range of the Pyrotechnic Separation process, including the detonation process, rocket fairing rupture and associated shock propagation to the upper-stage payload section.
  • Satellite Payload Shock Response and Safety
    PAM-SHOCK can simulate the High-Frequency Vibration Response due to a short duration pulse, which typically affects Satellite Payload or Vehicle Equipment Bay after the pyrotechnic cutting used to separate modules in spacecraft or rockets.

 

Aeronautics

  • Foreign Object Damage upon metallic and non-metallic components
    One strong request from the aircraft industry is to be able to simulate the high velocity impact response of primarily composite aircraft structures. PAM-SHOCK enables the predictive simulation of impacts from birds, hail and stones, which eventually can lead to “certification by simulation”. Accompanying ESI Group’s High Velocity Impact solution is a dedicated models library containing ESI Group proprietary bird models for birdstrike simulation.
  • Crashlanding / Splashdown of Fixed and Rotary Wing Aircraft
    Through several European Research projects, PAM-SHOCK developed design methodologies for aircraft survivability in crash through simulation techniques for both metallic and composite structures. Thus it successfully simulates aircraft crashlanding on hard or soft soil and helicopter splashdown for instance.
  • Onboard Passive Safety
    PAM-SHOCK can interface with ESI Group’s Fluid Dynamics solutions, in order to produce a fluid-structure interaction capability of unparalleled magnitude to provide the analyst with realistic simulation of the complex deformations a thin-walled aerospace structure can suffer under limit loads like internal explosions.
  • Engine Blade Containment
    PAM-SHOCK allows the simulation of turbine engine blade containment thanks to predictive material models (like elastoplastic shells and solids with EWK* damage and failure) included. Besides, it uses the Implicit module for the centrifugal blade pre-stressing initialization.

Defense

  • Performance of Munitions with respect to Explosion, Cratering, Kinetic Energy Penetration
    The defense industry requires munitions modeling and the simulation of kinetic energy penetrators. PAM-SHOCK allows for the modeling of detonation in general, the cratering in soil and the penetration/perforation of reinforced concrete. Finally, predictive high strain rate material models for metals coupled with the advanced modeling methods like SPH allows the evaluation of the performance of kinetic energy penetrators.
