Characterizing Elastomer Fatigue Behavior for Analysis and Engineering

Introduction

Elastomers are outstanding in their ability to repeatedly endure large deformations, and they are often applied where fatigue performance is a critical consideration. Because the macromolecular structure of elastomers gives rise to a number of unique behaviors, appropriately specialized methods are needed to characterize, analyze, and design for durability. This 3-day course provides the know-how for engineering durable elastomeric components and systems. The course includes live demos of typical behavior.

This workshop is held at the Axel Products facility in Ann Arbor, MI.


Workshop Outline

  • Elastomers as an engineered material
  • Stress-strain behavior: physics, phenomenology, characterization, and modeling

  • Physics of elastomer fatigue
  • Phenomenology of durability: strength, fatigue threshold, R-ratio effects, the Haigh diagram
  • Crack Nucleation and Fracture Mechanics analysis approaches
  • Factors that affect fatigue behavior
  • Material characterization for fatigue life assessment
  • Dealing with multiaxial loading Dealing with variable amplitude loading and damage accumulation
  • Finite Element modeling for fatigue life prediction
