Rubber Fatigue DOES NOT EQUAL Metal Fatigue: When Linear Superposition Fails

Fatigue analysis for rubber differs from that for metals in many ways.

This webinar discusses nonlinearity, specifically the nonlinear relationship between applied load inputs and the resulting stress/strain responses. 

Elastomers in applications exhibit many nonlinearities.  These include:

  • Constitutive behavior
  • Finite strains
  • Contact

The consequence is that linear superposition, which is widely used in metal fatigue analysis to scale and combine unit load case finite element solutions, does not work for rubber. Join us to see how Endurica’s Efficient Interpolation Engine (EIE) handles the nonlinearities so that you can get durability right. 

Your presenter is Endurica's founder and president, Dr. Will Mars. An international leader in the failure mechanics of rubber and elastomers, Dr. Mars has received numerous awards for his scientific contributions, is the author or co-author of 50+ peer-reviewed publications and holds four patents. His expertise spans the "special effects" of rubber and elastomers in material characterization, product evaluation, constitutive modeling, crack nucleation, fracture mechanics, and fatigue life prediction methods.

Near the end of the webinar, Dr. Mars will answer your rubber fatigue vs. metal fatigue questions to help you to get durability right!
