摘要

A biaxial load test specimen 10 includes a main body 11 having a plurality of through-holes 14 aligned along the axial directions of two load axes, that is, a first load axis S1 and a second load axis S2, orthogonal to each other; and four arms 12 extending from the main body 11 in the respective axial directions of the first load axis S1 and the second load axis S2, wherein each of the arms 12 has a plurality of slit grooves 16 extending, on respective extensions of the through-holes 14 aligned in the axial directions, along the respective axial directions.
