Theory and Application of fe-safe/Rubber™

Course Objective

The durability for an elastomeric product operating under realistic service conditions can now be computed from a Finite Element Analysis, with a proper account taken of rubber’s unique macromolecular structure and nonlinear mechanical behaviors.  This two-day class gives you the theoretical and practical know-how to select appropriate material models, to obtain accurate operating strains for analysis, to specify a fatigue analysis, and to interpret the results.  Each core concept is illustrated with a hands-on exercise using fe-safe/rubber.  After this course, you will be ready to use fe-safe/Rubber to analyze, diagnose and solve fatigue performance issues.
