Table showing: (a) the percentage of bricks with ratios of ε₁/|ε₃| > 1; (b) the number of bricks with ratios of ε₁/|ε₃| that change from a value > 1 (indicating tension) to a value < 1 (indicating compression) between the stiffest and least stiff trials in each set; (c) the number of bricks with ratios of ε₁/|ε₃| that change from a value < 1 (indicating compression) to a value > 1 (indicating tension) between the stiffest and least stiff trials in each set; (d) the net percentage of bricks changing loading regimes, with negative values indicating compressive forces increasing as stiffness decreases and positive values in bold indicating tensile forces increasing as stiffness decreases.
