Elastomers are outstanding in their ability to repeatedly endure large deformations, and they are often applied where fatigue performance is critical. Their macromolecular structure gives rise to unique behaviors, and so appropriately specialized experimental methods are needed to characterize, analyze, and design for durability. This course will give you powerful approaches to anticipate, diagnose and solve fatigue-related issues. Presented live online, in a multi-day workshop, this training gives you a deep-dive, hands-on experience in how to solve durability issues.

Characterizing Elastomer Fatigue Behavior for Analysis and Engineering

Course Details

Presented LIVE online over five sessions from 9:00 a.m. - noon EDT. As a special service to attendees, Dr. Mars will be available for individual questions during office hours from 1:00 - 3:00 p.m. daily throughout the week of the class.

You will learn Endurica's insights on

  • Elastomers as engineered materials 
  • Design, Analysis and Characterization for Durability with Rubber 
  • Stiffness, mode of control, compound optimization 
  • Stress-strain – molecular origins and hyperelasticity 
  • Stress-strain – cyclic phenomena and advanced models 
  • Self-heating in rubber
  • Tearing energy
  • Characterizing strength of rubber
  • The fatigue threshold
  • Strategic considerations in fatigue testing
  • Characterizing Fatigue behavior of individual cracks – fully relaxing cycles
  • Characterizing Fatigue behavior – nonrelaxing cycles and strain crystallization
  • Crack nucleation, S-N curves, Continuum Damage 
  • Characterizing crack precursor size
  • Rubber’s Fatigue Design Envelope 
  • Aging 
  • Multiaxial loading and Critical Plane Analysis
  • Fatigue in tension, shear, and compression
  • Variable amplitude loading, Rainflow counting, and damage accumulation
  • Component testing


The course features live lectures and exercises focused on specifying, executing and interpreting numerical simulations of fatigue behavior. This course is a LIVE training event and link to the presentation of each class will be made available to registrants for their reference/review. These links will be active for seven days after the class date so attendees will have time to make up classes they may not be able to attend live.   

Dr. Will Mars is an international authority on damage mechanics in elastomers. He brings two decades of experience developing product testing and simulation methods in the rubber industry. He is the editor of Rubber Chemistry & Technology.


Endurica LLC reserves the right to cancel a scheduled training course if the minimum class size is not met. In the event of a cancellation, Endurica LLC will make every attempt to notify registered participants within five working days. Payment made for a canceled course will be refunded in full or applied to another scheduled training course.

Participant cancellations must be received at least 10 working days in advance. Registrations canceled by participants less than 10 working days before the training course begins are subject to a 50% cancellation charge. For cancellations occurring on the first day of a scheduled training course, and for "no shows," the full tuition fee is non-refundable.
