Fatigue Crack Growth Testing Module

Advanced Testing for Quantifying Cracks in Elastomers

Resistance to fatigue, aging, and crack formation is a key concern in the development and application of rubber-like materials, especially in safety-critical industries such as tire manufacturing.

Traditional commercial testing methods typically focus on behavior up to failure, offering limited insight into actual crack propagation.

Since 1999, Metravib has been working closely with leading tire manufacturers to develop a variety of customized testing machines specifically for crack growth analysis.

Based on this extensive experience, Metravib has developed the Fatigue Crack Growth Testing Module – an advanced and efficient testing tool designed to provide the rubber industry and research community with quantitative crack propagation analysis.
