Applications of full-field optical methods in micro-mechanics and material engineering

Abstract

 Current trends in the development of micro-scale components, structures and systems place unprecedented requirements on their designers. To satisfy these demands, new experimental tools have to be employed along with the computational solutions. The biggest challenge includes the experimental knowledge of micromechanical behaviour of materials and to design validation of finished products. This information is provided by electronic holography and grating interferometry used as full-field, noninvasive experimental techniques. The usefulness of these methods are shown by several examples including the determination of local material properties of polycrystalline, composit and smart materials, as well as dynamic characteristic of structures.
