We investigated the mechanical properties of the felled beech wood trees (Fagus sylvatica L) after ice storm. The test material was taken from four different trees, differently damaged, at the three tree heights: at breast height, in the middle and just below the crown. Mechanical properties were studied in green and dried state, using parallel samples. Modulus of elasticity, bending strength, longitudinal shear strength and compressive strength were determined in all three anatomical directions by standard mechanical testinf and the dynamic modulus of elasticity by measuring the speed of ultrasound and frequency response. We have not yet confirmed the reduction in mechanical properties in the first growing season after ice storm. We found however significantly reduced all examined strengths of the wood from the juvenile- compared to adult wood, while the density from the pith toward the bark increased.
