Simultaneous radiographic observation of damaging and optical measurement of 3D surface displacement evolution in loaded specimen
 Vavřík, Daniel ; Bryscejn, Jan ; Jakůbek, J. ; Holý, T. ; Valach, Jaroslav ; Vykydal, Z.
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.

New Experimental Setup for Study of Physical Processes Preceding Specimen Failure
 Vavřík, Daniel ; Bryscejn, Jan ; Holý, T. ; Jakůbek, J. ; Jakůbek, M. ; Valach, Jaroslav ; Vykydal, Z.
Failure of a high ductile specimen usually precedes a decrease of the loading force under the condition of displacement control in the monotonic loading. Unfortunately, the elastic energy stored in the standard loading equipment can result in sudden failure within very short time corresponding to the loading unstability. We can prolong this time interval by reducing the elastic energy in the loading equipment. The proposed new loading frame fulfils the indicated requirement and enables extraordinary precise displacement loading control even beyond the maximal loading force. Plastic deformation on a surface is investigated by the optical Method of Interpolated Ellipses and together with damage processes inside of the specimen are simultaneously observed by the X-ray Dynamic Defectoscopy method.
