Impact, Shock & Crash Focus group

Impact, Shock & Crash Focus Group

The NAFEMS Impact, Shock & Crash Focus Group (ISCFG) is concerned with all aspects of Explicit Dynamics Finite Element Analysis (EDFEA), typically short time duration events which are highly non-linear in nature including impact, shock, drop test, blast and ballistics which are all solved using Explicit Solution Methods. All computational approaches are included (Lagrangian, Eulerian, Smooth Particle Hydrodynamics (SPH) as well as Single Degree of Freedom (SDOF), etc.) and the related technologies required whether for pre-processing (including meshing), solving or post-processing.


To promote the safe, reliable and effective use of simulation techniques for modelling Impact, Shock and Crash events by:

  1. Providing guidance and information for EDFEA users of all levels.
  2. Encouraging and supporting the increasing use of EDFEA within the international community.
  3. To help both users and managers to apply EDFEA techniques appropriately and usefully.
  4. To provide information for people using information from EDFEA simulations but who may not be performing simulations directly.

The focus is towards improving the effective use of EDFEA for industrial applications, regardless of where those simulations are performed (in industry, by consultants or vendors or in academia).
