<jats:p>Nowadays, nanoindentation is commonly applied to various materials to assess micromechanical properties.

It is shown in the paper, that different deformation mechanisms in tension and compression take place for the tested materials which is demonstrated by large differences between the measured nanoindentation moduli and macroscopic tensile elastic moduli. The situation is illustrated on several types of biological and man-made fibers.
