Title
Speckle photographic strain field measurement. A helpful aid in fracture modelling and analysis of microstructures
Abstract
By means of speckle photography displacements and strains of fracture specimen are measured methods of digital image processing are applied. The strain field of a CT specimen is measured in a small region around the cracktip. The method was also applied to an unnotched Al2O3 ceramic specimen.
