FIELD: mechanical engineering. SUBSTANCE: model is loaded with the aid of cylindrical indenter with length equal to thickness t of model and diameter within range 0.5- 10.0 thickness of model which is flush-mounted with flat surfaces of model at distance C equal to 0.1a-0.25a from point of application of force. Strain-gauge transducer used to measure value of relative deformation ε is placed before test, then modulus E of longitudinal elasticity is determined from relation E = 2P/πCtε, where P is force of action on sample directed along its longitudinal axis; a is characteristic dimension of model. EFFECT: enhanced functional reliability. 2 cl, 10 dwg
