BENCH TO INVESTIGATE ENERGY EXCHANGE IN RELAXATION OF STRESSES

摘要

FIELD: testing equipment.;SUBSTANCE: bench comprises a body, a matrix fixed on it with a curved slot and a pusher to move a sample along the matrix slot. The matrix is split, and the bench is equipped with a base of the matrix fixed on the body in a cantilever manner. One part of the matrix is fixed on the part of the base, fixed on the body, the other part of the matrix is fixed on the cantilever part of the base, at the same time the bench is equipped with a cam interacting with the cantilever part of the base, and a drive of cam rotation.;EFFECT: increased volume of information due to provision of investigations both in relaxation of sample bend stresses and in alternation of relaxation with cyclic loads of a sample with adjustment of unloading parameters in process of tests.;2 cl, 1 dwg
