In this article we deal with investigation a influence of cyclic loading massive and laminated beech wood at various material thicknesses on modulus of elasticity „Em“, during bending in radial direction. For identification of monitored characteristic we used static bending test with three-point loading. Monitored characteristic was detected on testing samples which weren’t cyclic loaded and our results were compared with other results obtained from samples which were cyclic loaded. The results of this work show that influence of cyclic loading on values of modulus of elasticity for laminated wood isn’t significant. On the other hand the cyclic loading has significant influence on decreasing of monitored values at massive wood. Thickness influence is significant factor; the results show that thickness increasing causes the lowering modulus of elasticity values after cyclic loading.
