DETERMINATION OF THE ELASTIC CONSTANTS OF BRICKS ON INDUSTRIAL SAMPLES IN FOUR-POINT BENDING TESTS

The paper considers a variant of determining the mechanical characteristics, namely elastic moduli and Poisson’s ratios, of building bricks in four-point bending tests of industrial samples and measurement of strains by fiber-optic sensors. An example of determining the elastic constants of one of the brick grades in tension and compression is given, with analyzing the maximum errors in the determination of the elastic moduli and Poisson’s ratios, which may occur in the method under consideration.
