Fast dynamics and crash

•  Discover the specific issues related to the modeling of materials and structures in fast and crash dynamics:
  -- explicit integration schemes in time
  -- geometric nonlinearities (large rotations, large displacements)
  -- nonlinear behavior of materials
  -- contact-friction
  -- specific finite elements
•  Use and parameterization of an explicit calculation code (Radioss)

•  Introduction to the analysis of mechanical systems in dynamics
•  Presentation of the HyperWorks software suite
•  Theoretical aspects:
  -- Time discretization (implicit/explicit, stability condition of the schemes)
  -- Discretization in space (finite elements and hourglass control)
•  Modeling choices:
  -- Behavioral relationships of different materials
  -- Contact modeling
  -- Addition of kinematic constraints and loads
 •  Practical application using a fast dynamics calculation code (HyperWorks/Radioss)
  -- Setting the data of the problem
  -- Choice and parameterization of algorithms
  -- Critical analysis of the calculation results

•  Know the theoretical specificities of fast dynamics
•  Know how to choose to build a model adapted to the treated problem
•  Know how to choose the algorithm adapted to the treated problem
•  Know how to analyze and criticize a calculation result
