wood, stress, strength, deformation, diagram, compression, dependencies.

A detailed analysis of the dependencies for the construction of σ-u diagrams of various coniferous and deciduous wood species for compression along the fibers by the national and foreign scientists was carried out. It is established that polynomial and irregular fractional-rational functions are the most acceptable for approximation of stress-strain diagrams of wood. These dependencies can describe the complete diagrams of deformation of wood on the ascending and partially on the descending branches. It is established that the most appropriate function for describing the stress-strain diagram is a 4th degree polynomial.
