Compression test of a timber core - ANSYS model and moire interferometry experiment
Micka, Michal ; Minster, Jiří ; Václavík, P.
The paper presents results of modelling a non-standard compression test of timber, executed on small diameter cores in a special testing device.The test is semidestructive - friendly to historic timber. Numerical solution for elastic orthotropic material is correlated with results of moire-intererometry experimental data. The approach enables to define strengths and Young´s moduli of the assessed core.
Holo-interferograms of dynamically loaded cylindrical shell and their interpretation
Trnka, Jan ; Václavík, P. ; Richterová, Ž.
Holointerferometry with a double pulse ruby laser as a light source was applied to record transient out-of-plane motion. Propagating bending waves were studied in the shells made of steel. a focused ruby laser beam caused short impact loading. the method based on the nonparaxial imaging equations and on the holographic impaging equations by using of the Ennos procedure was developed to evaluate the holointerferograms.
Deformation Analysis of Bimaterial Interfaces Using Moire-Interferometry
Minster, Jiří ; Fiala, Zdeněk ; Václavík, P.
The paper presents some results of experimental verification of analytical-numerical determination of interface fracture toughness using a bimaterial Brazil test model. Evaluation and interpretation of interferograms, continuously recorded from the beginning to the fracture of specimens, approved the used modelassessment of non-stability caused by initiation and propagation of interface.
Experimental Analysis of Kinematic and Deformation Characteristics of a Fatigue Crack
Berka, Ladislav ; Horečka, L. ; Běhal, J. ; Minster, Jiří ; Václavík, P.
The kinematics and the deformation characteristics are analysed during the fatigue crack grouth under random cyclic loading accross the strip specimen. The stereoimage technique and the moire interferometry were used to analyse plastic strain distribution ground the crack. The resulting values, that follow from both methods are in good agreement.
