摘要:
FIELD: construction.SUBSTANCE: invention relates to the field of construction, in particular to the test of samples for eccentrical compression. Essence: one performs drilling on the upper and lower support surface of a quadrangular prism of symmetrical paired spherical holes for centering elements, one pair of which are placed along its longitudinal axis. Core of the prism section is determined and additional two pairs of spherical wells are drilled, three pairs of spherical holes are placed along the boundary of the core of the section, and the middle part of the prism equal to at least 1/3 of its length is made in the form of an equilateral I-beam.EFFECT: accuracy increase in the stress state indicators of the sample material in the case of eccentric compression.1 cl, 2 dwg
