Abstract
The apparatus comprises a fixed frame 1 with a pair of lateral guiding uprights 2 for at least one variable- inclination beam 3 and a succession of supports 6 for lower bearing surfaces 7 for the test-pieces, which are slidably supported by the beam 3 and which have, associated with them, means for determining the force and therefore the elasticity modulus, said means co-operating with at least one fixed upper bearing surface 10 arranged longitudinally along the frame and fixed at its ends to the uprights 2 for bending the series of test-pieces 8 with a variable radius of curvature depending on relative raising of the lower bearing surfaces 7 with respect to the upper bearing surfaces 10. Sliding of the supports 6 with respect to the beam 3 is guided by a pair of lateral guides 11 and the variable inclination of the beam 3 is achieved by means of controlled-speed motor groups 16.
