FIELD: testing equipment.
SUBSTANCE: ends of the samples are fixed on the support, bent and the amount of deflection is determined under conditions of complex bending. The support is made in the form of a closed frame with two movable spacers, and loading is carried out by means of a loading hydraulic cylinder that transfers pressure to the compressing or expanding hydraulic cylinder, which deforms the support in the horizontal plane. The nominal stress level is created in the sample and spacer design, which is proportional to the transverse load on the sample.
EFFECT: possibility of testing the samples under conditions of complex bending with the variable in the process of loading the level of nominal stresses and the thrust ratio, depending on the magnitude of the lateral load, applied to the sample.
