This class provides an introduction to failure predictions of rubbers and thermoplastics using FEA. The training class is targeted to people with an interest in experimental testing and failure modeling of polymers using a finite element program.

By the end of the class you will:

  • Know the most common failure modes of engineering polymers.
  • Know how to experimentally characterize the failure behavior of a polymer.
  • Calibrate and run both simple and more advanced failure models within a FE simulation.


The training class is indented for people with experience running finite element simulations of different polymers (rubbers, thermoplastics, thermosets, biomaterials, etc). It is recommended, but not necessary, to have taken one of our introductory polymer modeling classes (e.g. Finite Element Modeling of Solid Polymers (Part 1)).

Course Outline

  • Experimental testing techniques for failure characterization.
  • Review of theory for fatigue, ductile failure, and brittle failure.
  • Techniques for incorporating failure into a FE simulation.

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:

Course Materials

Everyone who registers for the class will receive a free one-month license to the MCalibration software, and a one-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.

Previous Attendees Had This to Say…

Great value. Two days of training saved weeks of engineering work.

  • “I gained a tremendous amount of knowledge on topics which would normally be taught in a semester-long course.”
  • “Very valuable for design engineers running FEA on thermoplastics and elastomers.”
  • “Gained a good overall introduction to the mechanics of polymers.”
  • “I would highly recommend this class to my students.”
  • “Will/has helped us revisit legacy material modeling and material testing.”
