FIELD: instrumentation engineering. ^ SUBSTANCE: proposed apparatus has loading device, supports, and device transferring load to specimen through hold-down plates. Device transferring load to specimen is made in the form of halved hollow ball, each half having trihedral depression. Hollow ball is mounted between top and bottom supports; top and bottom plates of press perform function of loading device; ball bearing is disposed between top support and top plate of press. ^ EFFECT: facilitated test procedure, enhanced precision of test results. ^ 1 cl, 1 dwg |
