Optical methods in experimental mechanics
Hrabovský, Miroslav
The paper deals with experimental methods used in experimental mechanics, especially in experimental stress analysis. High attention is given to optical methods - classical and modern optical methods and its future in mechanics. They are classical interferometry based on optical interference and superposition, stereometry, photoplasticity, moiré, holography speckle photography etc.

Nd:YAG pulsed laser cutting of metals
Chmelíčková, Hana ; Polák, Marek
Pulsed Nd:YAG laser KLS 246-102 with average power 150W was developed for cutting, drilling and welding of metal and non-metal materials with thickness up to 2 mm. We chose an usually used kind of metal, steel (class 11) to test the optimal cutting conditions on various thickness from 0.1 to 1 mm.
