Interesting that you mention the length scale - we use the same principle when we produce high classes of steel ... we produce the steel as very small grains within this small grains there are next to no matrix failures ... and then the grains are sintered together under very high pressure (without distrubring the matrix) this way we can reach incredible tensile strength up to 2000 N/mm2 (Random information No 2036)
From ASTM D7012-14: "8.1.1 Desirable specimen length to diameter ratios are between 2.0:1 and 2.5:1. Specimen length to diameter ratios of less than 2.0:1 are unacceptable". Triaxial testing with short samples L

Thanks I did not know that! Thus spoke DNE
Fantastic job! maybe the height to width ratio (i.e., shape effect) should be involved in the factor of brittle to ductile transition.
