Accurate FEA of Engineering Plastics - Keynote

This presentation is the Keynote Address given CAE Associates' Accurate FEA of Engineering Plastics seminar, held on October 14, 2014 in Tarrytown, NY.

Keynote speaker Hubert Lobo is President & Founder of DatapointLabs, with over 25 years experience understanding nonlinear material behavior and how it impacts product design, provides an introduction to the stress-strain characteristics of polymers: rubbery, ductile, and brittle plastics, along with special considerations required to successfully analyze each type.

Keynote Topics:

  • Using elasto-plasticity
  • When to use hyperelasticity
  • Brittle polymers – filled plastics
  • Failure modes to consider
  • Criteria for survival
  • Choosing materials
  • Spatial non-isotropy from injection molding
  • Importance of residual stress
  • Visco-elastic and creep effects
  • Strain-rate effects for drop test and crash simulations
  • Fitting material data to FEA material models
