Title:
Experimental methods of concerning the determining relations with the use of cylindrical samples
A program of experiments is proposed for specifying the defining relations for a cylindrically anisotropic material. The program assumes four experiments using cylindrical samples: extension of a solid cylinder, distribution of a hollow, thick-walled cylinder with internal pressure, cylindrical and longitudinal shear. Expressions for the defining relations of a cylindrically- orthotropic material are obtained. The considered variant of nonlinear defining relations between stresses and deformations in anisotropic materials satisfies the limiting form of the generalized particular postulate AA. Ilyushin. The functions in the defining relations are assumed to be linearly dependent on the material constants. The obtained dependencies relate the characteristics and material constants measured during the experiments. Solving equations can also be used to solve a more complex problem: the determination of nonlinear functions from the results of measurements from a larger number of points.
