Box Plots, Failure loads and Stiffness, adjusted (inidvidualized) setting vs. fixed span during three-point bending. a Failure loads of individual (adjusted) vs. fixed (15 mm) setting during three-point bending. A strong tendency (p = 0.07) to obtain different results by altering the setup was evident. Furthermore, the standard deviation within the sample was lowered by individual adjusted loading bars (18.95 N vs. 30.4 N, see Table 2). b Stiffness values of individual (adjusted) vs. fixed (15 mm) setting during three-point bending. Highly significant difference (p < 0.0001), the standard deviation of the adjusted sample was only about one third compared to fixed bars (34.6 N/mm vs. 104.8 N/mm)
