Abstract
The influence of the drying process conditions on the deformation of the beech and oak wood. The results of the deformation of beech wood (Fagus sylvatica L.) and oak wood (Quercusrobur) after drying process are presented. The drying process was carried out in the same drying schedule for each wood species. During each of schedules 40 pieces of wood were dried. The samples were divided into two groups. The first group of tested wood (30 pieces) was dried under a uniform distributed load of 40 kg, while the second group was dried without load (10 samples). These specimens were selected taking into consideration different angle of the growth rings (radial and tangential), containing tension wood. Subsequently findings show that lamellas drying under load had much less deformation of the cup, bow and twist typein comparison to lamellas dried without load.Cracks that have occurred in dried lamellas proved to be comparable in the case of drying under and without load.
