Title: Experimental method for register of the deformations
Keywords: Grid method, experimental method for register of the deformations
Abstract: The description of an experimental method for register of the deformations as well as some modification of the numerical procedures in the stage of post processing is the subject of this work. Mathematical formulation of the numerical procedures is presented in details. The experimental method is based on optical monitoring of deformation during loading process. Hexagonal grid of dots is deposited on the surface of the specimen. Loading the specimen deforms an initial circle on the surface into an ellipse. Ellipse parameters are obtained by digital image processing. Knowledge of the ellipse parameters directly produces the magnitude and the direction of principal strains on the monitored specimen surface.
