CASE STUDY
The article focuses on the difference in fatigue behaviour between rubber and metal materials. While metal fatigue is often described by a simple rule: increasing mean strain is detrimental to fatigue life, rubber fatigue is more complex and depends on the material's ability to strain crystallize. The text concludes that while tensile mean stresses are always detrimental in metals, in rubber they may be either beneficial or harmful depending on whether the rubber can strain crystallize.
