Explicit Dynamics FEA in the Fields of Impact, Shock & Crash

Explicit Dynamics FEA in the Fields of Impact, Shock & Crash

Explicit Dynamics Finite Element Analysis has been used by industry and academia for many years. With advanced techniques such as particle methods, Arbitrary Lagrangian-Eulerian and advance failure methods becoming more prevalent in general purpose simulation packages, simulation engineers have never had such capabilities at their fingertips.

Modelling impact, shock & crash phenomenon is inherently difficult. The process is highly non-linear, materials are strain rate dependant, damage has to be realistically represented in order to capture the response of the product. The aim of this seminar is to present and discuss the challenges, and solutions in this field, using real engineering examples.

Seminar Themes

  • Wave Propagation (Shock Pressure, Gas Pressure)
  • Non-Linear Material Behaviour (Strain-Rate Dependencies, Damage & Failure Mechanisms)
  • Fragmentation
  • Explosive/Vapour Cloud Blast Simulation
  • Crash & Drop Testing
  • Contact/Penetration Mechanics
  • Adaptive Mesh Refinement & Rezoning
  • Eulerian – Lagrangian Methodologies (ALE)
  • Smooth Particle Hydrodynamics (SPH) Methodologies
  • Equations of State
  • Crash Test Dummy, Seat Belt, Barrier, Spot Weld & Rivet Models
  • Reinforced Concrete, Laminated Glass and Composites Modelling
  • Understanding Energy Balances
  • Hourglass Effects
  • Time Step Controls, Mass Scaling
  • Implicit – Explicit – Implicit Analysis Sequencing
  • Benchmarking
  • Validation

The list could go on, and is applicable to all of the typical analyses across a number of different industries, from automotive to electronics and everything in between. This seminar has been organised by the Impact, Shock & Crash Working Group and the Computational Structural Mechanical Working Group. NAFEMS recently created the ISCWG in order that knowledge of state-of-the-art explicit dynamic methods may be disseminated across the broader simulation community. The ISCWG would like to use this initiative to reach out to potential new members, to hear about the needs of industry.

If you have experience using these methodologies and techniques we would like to invite you to make a brief (25 minutes + 5 minutes Q&A) presentation at this, our first seminar, in hopefully a series over the coming years.

Who should attend?

  • Design engineers who wish to learn how to access the performance of their products under dynamic loadings
  • CAE Managers and Practitioners who want to learn about state of the art techniques
  • Engineering managers who want to learn about the benefits that can be realised by investing in an explicit dynamics capability
