Abstract
The invention relates to an arrangement and to a method for the synchronous determination of the shear modulus and of the Poisson's number on samples of elastically isotropic and anisotropic materials. In the arrangement, an indenter is movable in parallel with its longitudinal axis (A) in the direction of the surface of a sample such that a force action is exerted on the material by its tip. The force can be determined by a device for measuring this force and the indenter is additionally deflected in translation along at least one further axis. The longitudinal axis (A) of the indenter is aligned at an angle ≠90° with respect to the surface of the sample and the indenter carries out an upward movement and a downward movement. In this respect, a device is present for calculating the shear modulus G and the Poisson's number v from the contact stiffness k determined in this manner, from the acting normal force P, from the indentation modulus Mand from the shear modulus-related parameter Nof the sample while taking account of the respective angle θ.
