In order to describe the behaviour of wood when calculating wooden elements and structures with the use of the finite element method, orthotropic material model in combination with non-interactive (maximum stress criterion) or interactive failure criteria (Hoffman and Tsai-Wu criterion) is used. Another option is to use a general anisotropic plasticity material model complemented with a non-interactive failure criterion – maximum stress criterion, which allows to describe wood failure by brittle failure in tension. The presented general material model was used in combination with the idealization of annual rings by cylindrical surface for the modelling of wood specimen tests form Scots pine (Pinus sylvestris). The obtained results show good agreement between the results of numerical analysis and experimental testing of wood specimens. The use of the anisotropic material model can also be seen in cases when the level of the applied load is higher than the level when the failure of wooden material occurs.Radi objašnjenja ponašanja drva pri proračunima drvnih elemenata i konstrukcija primjenom metode konačnih elemenata, upotrijebljen je model ortotropnog materijala u kombinaciji s neinteraktivnim kriterijem (kriterij maksimalnog naprezanja) ili interaktivnim kriterijima loma (Hoffmanov i Tsai-wuov kriterij). Druga je mogućnost upotrijebiti opći model za anizotropno-plastične materijale dopunjen neinteraktivnim kriterijem loma – kriterijem maksimalnog naprezanja, koji omogućuje objašnjenje lomljivosti drva pri naprezanju. Predstavljeni opći model materijala u kombinaciji s idealizacijom godova kao cilindričnih površina upotrijebljen je za modeliranje uzoraka izrađenih od drva običnog bora (Pinus sylvestris). Dobiveni rezultati pokazuju dobru podudarnost rezultata numeričke analize i rezultata eksperimentalnih ispitivanja uzoraka drva. Model anizotropnog materijala primjenjiv je i kada je opterećenje veće od onoga pri kojemu dolazi do loma drvnog materijala
