摘要
The invention relates to an arrangement and method for the synchronous determination of the shear modulus and the poisson''s ratio of samples, isotropic and anisotropic materials made of elastically. In the case of the arrangement is an indenter parallel to its longitudinal axis (a) in the direction of the surface of a sample can be moved such that, with its tip, a force effect is exerted on the material. The force by means of a device for measurement of this force can be determined, and the indenter is translationally along at least a further axis, in addition, deflected. The longitudinal axis (a) of the indene is in relation to the surface of the sample in an angle ≠ 90° aligned, and the indenter a leads to - and a downward movement of. In this case, a device for the calculation of the shear modulus g and the poisson''s ratio v, from the thus determined contact stiffness k, of the acting normal force p, the impression of the module mS and the shear modulus - related parameter nS the sample taking into account of the respective angle θ, present.
