Abstract: [eng] [cze]
Article deals with material properties of spongy bone assessed by optical identification based on surface texture registration.Strains at the specimen surface were measured using high-resolution CCD camera and optical identification method was used to trace their position during deformation. Centres of gravity of the markers are then considered to be vertices of connected triangles for which fields of displacement and strain are calculated. The assessed displacements of the structure of trabecular bone are used to obtain strain-stress diagram. Článek se zabývá použitím optických identifikačních metod měření deformací vzorků pří tahových/tlakových zkouškách. V tomto případě se jedná o zjišťování materiálových vlastností spongiózní kosti.
