BENDING STRENGTH AND PROPORTIONALITY LIMIT OF CYCLIC LOADING ON BEECH AND ASPEN SOLID WOOD

Original language description

This paper is aimed to investigate the influence of the used wood species (European beech - Fagus Silvatica, quaking aspen - Populus Tremula L), used sample thicknesses (4, 6, 10 and 18 mm), wooden mass compaction degree (10% and 20%) and cyclic loading (0 or 10,000 cycles) on the breaking strength (ap) and proportionality limit (sigma u) as the features to be evaluated. For the breaking strength, the statistically significant factors are the following: wood species, thickness, compaction and the combination wood species thickness. The remaining factors and their interactions are not statistically significant. As evident from the measured values, the wood species factor is influencing the bend breaking strength, with the beech samples having an average bend breaking strength higher by 31,1% than the aspen samples. The bend breaking strength of the wood is increasing with its compaction degree. The breaking strength increases with the cyclic loading. Wood species, thickness, compaction and number of cycles are statistically significant factors influencing the proportionality limit. From among the combination of two factors, the following combinations are significant: wood species thickness and wood species compaction. Statistically irrelevant are the following combinations: thickness compaction, wood species number of cycles, thickness number of cycles and compaction number of cycles. Three-factor analysis has shown the statistically significant interaction of the factors wood species thickness compaction. The remaining three-factor interactions are not significant. The combination of all four factors is statistically significant.
