Abstract
In a method of detecting damage in materials or objects () the material or object is physically influenced to produce a physical change of the material or object inducing transient slow dynamics in case of damages in the material or object. Slow dynamics induced material elastic modulus changes are detected as indication of damages of the material or object. In a device for non-destructive detection of damage in materials or objects (), an impact source () is provided to impact the material or object to physically influence the material or object to produce a physical change of the material or object inducing transient slow dynamics in case of damages in the material or object. A detector () is provided to detect by said slow dynamics induced material elastic modulus changes as indications of damages of the material or object.
