Název v původním jazyce

Non-destructive observation of damage processes by X-ray Dynamic Defectoscopy

Popis výsledku v původním jazyce

Recent theoretical models of the ductile fracture mechanics describe the dynamic development of voids and micro-cracks in materials under plastic deformation. For these models, experimental verification is needed. Thanks to the project Experimental and Numerical Identification of Damage in Ductile Materials a new, unique, direct and nondestructive experimental method X Ray Dynamic Defectoscopy (XRDD) was developed. This technique enables to overcome the obstacles of current approaches to determine the distribution of local variations of material density with micrometric accuracy while nondestructively following in real time the generation of these processes. The test sample is illuminated by X rays during the loading process. Changes in transmission indicate effective alterations in the sample thickness which is understood as weakening of the material due to void volume and thickness reduction (contraction) as a result of loading stress
