Annotation:

A model of the physical and mechanical properties of wood with the finite element analysis is offered. The method is based on the strength of wood samples of different species using finite element method, taking into account the anisotropic properties of the wood is offered. The numerical study of the wood sample in tension in order to determine the tensile strength of various breeds was carried out.

Key words:

physical and mechanical properties, ultimate tensile strength, modulus of elasticity, finite element method
