Mechanical failure of materials can have catastrophic consequences for companies and can endanger the security of persons. Despite these risks, visual inspection using a microscope is today the only tool available to determine the root causes of failure.

Tortoise revolutionizes the field of failure analysis: with a simple scan of the broken piece, access to quantitative information about the conditions of failure and the properties of the broken material.


To prevent failure risks and improve your reliability, make the most of past incidents. Use Tortoise’s technology to reach a quantitative understanding of past mechanical failures.


Our technology

Tortoise co-founders Laurent Ponson and Stéphane Vernède [1,2] have developed a revolutionary method that deciphers the morphology of the new surfaces formed by the failure of a material. The method builds on 30 years of research on material failure and generates information like the failure load or the resistance of the material, which were previously inaccessible. This patented technology allows to trace back the history of a failure with an unprecedented precision and thus facilitate greatly the determination of its root causes.[3]
