Abstract

There are great impact forces in mechanized harvesting and wood yard in the mills which can cause breaks in timber. The impact strength of timber in green condition was tested in temperatures of +18Â°C and -18Â°C using sawn pieces (20 x 20 x 300 mm) of Scots pine ( L.), Norway spruce ( (L.) H. Karst.), birch ( Roth and Ehrh.), grey alder ( L.) and aspen ( L.). In addition, unbarked naturally round sticks (length 300 mm, diameter 15 and 35 mm) of the same species were tested.Pinus sylvestrisPicea abiesBetula pendulaB. pubescensAlnus incanaPopulus tremula
