Hendrik Seipt: Ultrasonic Tomography at historical stone objects combined with a virtual 3D - Model Back
Language: Original   -   Translation
Overview:  
Abstract: Ultrasonic tomography was used as a non-destructive technology on stone objects.
There for laboratory-technical investigations of a marble piece took place with consideration of the elastic anisotropy. The tomographical computed ultrasonic speeds were compared with grid-pattern measurements of the biaxial bending tensile strength and examined for its correlation.
The method was accomplished at three historical stone objects, the investigation of a fissure - damage at a marble sculpture, the investigation of a marble capital on the phenomenon of the structural interior decomposition and an ultrasonic tomography at a monumental sculpture from rose granite. Capital and monumental statue became measured with the 3D - fringe-projection method. For the statue the result is a 3D similar representation with sectional views. The tomography of the Capital was coupled to a revolving virtual 3D-model.
