This two-day web-based course covers a review of polymer mechanics theory, techniques and tools for experimentally characterizing polymers, and hands-on training on how to perform accurate finite element simulations of polymer components. The training class is targeted to people with an interest in designing and analyzing the mechanical performance of parts made from plastics, rubbers, thermosets, or other types of polymers.

By the end of the class you will be able to:

  • Design a relevant experimental test program for a new polymer material.
  • Know the strengths and weaknesses of various material models, and be able to select an appropriate material model for finite element simulations.
  • Use experimental data to calibrate the selected material model.



The training class is indented for people with some experience running a finite element program. The examples presented in class will use the finite element programs Abaqus and ANSYS. The material models presented in the class are available for almost all commercial FE codes, including Abaqus, ANSYS, LS-DYNA, MSC.Marc, and COMSOL.

Course Outline

  • Review of polymer mechanics
  • Modern mechanical testing of polymers
  • Review of elasticity and hyperelasticity
  • Review of viscoelasticity theory: when to use linear viscoelasticity
  • Review of metal plasticity theory: strengths and limitations of metal plasticity models
  • User-material models in FE models, including advanced viscoplastic constitutive models incorporating rate and temperature dependence
  • Advanced finite element simulations of different classes of polymers
  • Material parameter extraction techniques using MCalibration and the PolyUMod library of user material models

About the Instroctor

Dr. Bergstrom is a Principal Engineer at Veryst Engineering, LLC, and consults primarily in the modeling, testing, and failure analysis of mechanical behavior of polymer materials.  He is the author of Mechanics of Solid Polymers: Theory and Computational Modeling, a comprehensive book that explains how solid polymers behave, how they can be experimentally characterized, and how to predict their behavior in different load environments.

Dr. Bergstrom received his Ph.D. from M.I.T. in the area of computational polymer mechanics, and has lectured in the Department of Mechanical Engineering at M.I.T. Dr. Bergstrom is the creator of the website: PolymerFEM.com.

Course Materials

Everyone who registers for the class will receive a free 1-month license to the MCalibration software, and a 1-month license to the PolyUMod Library of user-material models. A license to a FE program, like Abaqus or ANSYS, is not provided. Extensive training class notes will be provided in pdf-format. Notes are for personal use and may be printed, but cannot be modified, shared, or redistributed.
