Abstract

Određivanje tlačnih svojstava drva provodi se prema normi (DIN EN 408) u kojoj su specificirani uvjeti izvođenja eksperimenta i dimenzije samih uzoraka. Obzirom da je drvo heterogeni biopolimerni materijal, njegova mehanička svojstva ovise o dimenzijama samog uzorka. U ovom završnom radu određena su tlačna svojstva za tri različite vrste drva (hrastovina, bukovina i jelovina), te je unutar svake vrste drva određena ovisnost tlačnih svojstava o dimenzijama uzorka

Abstract (english)

The determination of the compressive properties of wood is carried out according to the standard (DIN EN 408), which specifies the conditions for performing the experiment and the dimensions of the samples themselves. Given that wood is a heterogeneous biopolymer material, its mechanical properties depend on the dimensions of the sample itself. In this final paper, the compressive properties were determined for three different types of wood (oak, beech and fir), and within each type of wood, the dependence of the compressive properties on the dimensions of the sample was determined.
