Quantitative fractography From roughness to toughness Laurent Ponson and Stéphane Vernède, co-founders of Tortoise, have invented a method that deciphers the morphology of new surfaces formed by the failure of a material. The method is applicable from a small fragment (typically 1mm3) of any material.Tortoise develops technologies for the application of the patented method in the fields of material characterization, predictive maintenance and failure analysis Simple workflow Broken sample Height map acquisition Processing Data display Example of report (EN) Example of report (FR)
