	Mikroradiografické pozorování pole napětí v blízkosti čela trhliny Vavřík, Daniel ; Jandejsek, Ivan ; Jakůbek, J. ; Jakůbek, M. ; Holý, T. Studies concerning ductile fracture mechanics require information about strain field in vicinity of the crack tip. Although it is a quite common problem new challenges occur when we are interested in strain field in micrometric scale, especially in the situation of mixed plane stress-strain mode in vicinity of the crack tip. Micro-radiographically visible structures of alloys or composites can be utilized as markers for such measurement using method of Digital Image Correlation. Detailed record
	Použití intenzity světla pro měření hloubky Valach, Jaroslav ; Bryscejn, Jan ; Vavřík, Daniel An uncommon optical method for depth measurement is presented. An interesting feature of this method is independence of its results accuracy on distance of the measured object to measuring device. Detailed record
	Užití digitální obrazové korelace v experimentální mechanice Jandejsek, Ivan ; Vavřík, Daniel The paper presents utilization of Digital Image Correlation methodology in experimental machanics. Benefits and new possibilities of DIC measurement in comparison with standard methods are presented. Detailed record
	Určování materiálových charakteristik pomocí digitální obrazové korelace Jandejsek, Ivan ; Vavřík, Daniel The paper presents the application of Digital Image Correlation (DIC) methodology for evaluation of optical data acquired during loading test. DIC allows to measure specimen surface deformation fields. Benefits and new possibilities of DIC measurement in comparison with standard methods will be presented. Detailed record
	Mechanické vlastnosti trabekulární kosti zjišťené pomocí voxelových MKP modelů a nanoindentace Jiroušek, Ondřej ; Vavřík, Daniel ; Jakubek, J. ; Dammer, J. ; Němeček, J. Article presents a combination of experimental and computational approach to determine apparent modulus of elasticity of trabecular bone. Voxel FE models with voxel size of 15 µm3 are used to calculate the overall material properties. Detailed record
	Metoda interpolovaných elips založena na digitální obrazové korelaci Vavřík, Daniel ; Jandejsek, Ivan This paper presents the application of Digital Image Correlation (DIC) methodology for the measurement of strain fields using the Method of Interpolated Ellipses (MIE). It will be shown that MIE has the ability to measure strain fields with higher Signal to Noise Ratio in comparison with standard approaches of the strain field measurement. Consequently MIE is less sensitive on the measurement inaccuracy which is always present in real experiments. Detailed record
	Optické měření modulu pružnosti pomocí digitální obrazové korelace Jandejsek, Ivan ; Vavřík, Daniel This paper presents the utilization of Digital Image Correlation Methodology for measuring of elasticity modulus in compression demonstrated on lime-mortar specimen. Benefits of Digital Image Correlation measurement in comparison with standard methods will be presented. Detailed record
	Korelace mechanických vlastností trabekulární kosti a její mikrostruktury za použití micko-CT a nanoindentace Jiroušek, Ondřej ; Vavřík, Daniel ; Jakubek, J. ; Dammer, J. For the investigation of trabecular bone microstructure and its relation to bone failure a combined approach utilizing FE models of the microstructure and compressive tests of small cylindrical samples is presented. Detailed record
	Digital Image Correlation Jandejsek, Ivan ; Vavřík, Daniel This paper presents the optical Digital Image Correlation method for in plane displacement field measurements. This method is based on tracing random structures, which are defined either by a sprayed pattern or by its own specimen surface structure. The displacements fields are obtained by measuring the mutual displacements of structure traced templates. The methodology for sub-pixel displacement measurements is presented. Detailed record
	Radiographic Observation of Strain Field and Consequent Damage Zone Evolution Vavřík, Daniel ; Jakůbek, J. ; Jandejsek, Ivan This work reports on results of the radiographic observation of 3D displacement/strain field and consequent damage evolution during loading of specimens with recognizable inner structure. In-plane deformations are evaluated from radiographs using the image correlation technique. The out-of plane displacement field is measured thanks to an accurate radiograph intensity to material thickness calibration. Detailed record
