Simultaneous radiographic observation of damaging and optical measurement of 3D surface displacement evolution in loaded specimen


Abstract eng:
This work reports on the results of the experimental observation of generation and evolution of internal material damage during loading process in aluminium alloy flat specimen with stress concentrator. Material damage is investigated by means of the “X-ray Dynamic Defectoscopy” technique. To understand related physical processes, the surface plastic strain field is investigated by the optical Method of Interpolated Ellipses while the out-of plane displacement field is inspected simultaneously by the optical Coded photometric stereo method. Related experiments have been realized using unique experimental setup which consists of microfocus X-ray source, compact loading device, CCD camera, LED red-green-blue lights and single X-ray photon counting device Medipix-2.
