To examine the low cycle fatigue properties of laminated beech, compression-compression test are carried out in the direction parallel to wood grain. A test specimen has shallow notches in order to avoid the die-test piece interface fractures. Experimental results show that the critical number of cycles to fracture becomes smaller with increasing magnitudes of the strain increment, althongh the scatter of its values is observed to some extent. Furthermore, it is found that typical fracturing pattern is type of a inclined straight-line originating from the root of a groove.
