The presented article deals with the influence of the drying process on the micro-mechanical properties of the composite middle lamella. The purpose of the composite middle lamella is to connecti individual cells. Micromechanical properties were obtained using nanoindentation and directly continuous stiffness measurement technique. Indentation modulus of tested samples was 11.45 GPa for natural dried wood and 12.51 GPa for artificial dried wood.

Versus Strain

Accurate determination of the “zero point,” the first contact between an indenter tip and sample surface, has to date remained elusive. In this article, we outline a relatively simple, objective procedure by which an effective zero point can be determined accurately and reproducibly using a nanoindenter equipped with a continuous stiffness measurement option and a spherical tip. The method relies on applying a data shift, which ensures that curves of stiffness versus contact radius are linear and go through the origin. The method was applied to fused silica, sapphire single crystals, and polycrystalline iron with various indenter sizes to a zero-point resolution of ≈2 nm. Errors of even a few nanometers can drastically alter plots and calculations that use the data, including curves of stress versus strain.
