Endurica CL for Elastomer Fatigue Analysis: The Key to Durability in Design

Endurica CL for Elastomer Fatigue Analysis: The Key to Durability in Design

In today’s automotive, defense, energy, and medical industries, the reliability of rubber (elastomer) components is one of the most critical factors directly affecting product quality and brand reputation. Endurica CL is a globally recognized, advanced engineering software developed to accurately and efficiently predict the fatigue life of elastomer materials.

In this article, we will answer the questions: What is Endurica CL, how does it work, in which industries is it used, and how does it add value to the design process?

 

What is Endurica CL?

Endurica CL (Core Lifetime) is specialized software focused on elastomer fatigue analysis.
The user inputs the Finite Element Analysis (FEA) loading history and material characterization data into the software. Endurica CL processes this data to determine how long the component can operate reliably, identify areas at risk of crack initiation, and pinpoint the loading conditions that shorten its life.

Key Features:

  • FEA code independence: Works with common FEA software such as Abaqus, ANSYS, and MSC/MARC.
  • Critical plane analysis: Determines the most vulnerable crack orientation under multiaxial loading.
  • Rainflow counting: Accurately classifies variable-amplitude load cycles.
  • Advanced material models: Incorporates realistic behaviors such as stress–strain curves, strain crystallization, temperature, and rate effects.

 

How Does It Work?

Endurica CL estimates fatigue life in three main stages:

  1. Data Input
    • Stress/strain time history from FEA results
    • Material fatigue properties (S–N or ε–N curves)
    • Operating environment conditions (temperature, speed, environmental effects)
  2. Analysis
    • Multiaxial loading evaluation using the critical plane method
    • Cycle counting with the rainflow method
    • Damage accumulation over time (Miner-Palmgren rule)
  3. Results Reporting
    • Predicted service life (in cycles or hours)
    • Visualization of the most critical regions (Haigh diagram, life maps)
    • Identification of damaging load conditions

 

Where Is It Used?

Endurica CL is used in all industries where elastomer component design is critical, including:

  • Automotive: Suspension bushings, engine mounts, seals, tire components
  • Defense: Suspension elements for armored vehicles, vibration isolation parts
  • Energy: Wind turbine seals, industrial hoses, vibration dampers
  • Medical devices: Elastomer diaphragms, sealing elements
  • Industrial machinery: Conveyor belt systems, vibration isolators
