Vliv teploty vzduchu na vybrané mechanické vlastnosti dřeva

Abstract

The bachelor thesis deals with the selected mechanical characteristics of spruce wood, Piceaabies in Latin. Thanks to the experimental methods, the mechanical characteristics of spruce wood in the pressure in the direction of fibres were determined. Subsequently, the module of elasticity in the pressure in the direction of fibres was determined. At laboratory tests, the influence of low temperatures was observed. Small defectless trial bodies were faced with the temperatures of -18 ºC, -5 ºC, 5 ºC a 20 ºC. Subsequently, the influence of these temperatures on the solidity in the pressure in the direction of fibres and on the module of elasticity in the pressure in the direction of fibres was observed. The observed results of the experimental measurement are processed with help of statistical methods tables. For quicker orientation and overview, they are processed in the form of tables and graphs. The results are mutually compared.
