Research is the viscoelasticity properties composite of wood made by gluing beech peeled veneer and at constant load, and two constant humidity. Based on the experimental results obtained by the method of the least squares rheological parameters have been determined as well as their differences in relation depending on the moisture content of samples. Has been developed and applied numerical model based on the finite volume method analysis of viscoelasticity properties composite of wood. Starting with the continuum concept we presented and broadened the application of the finite volume method for solving of the hygro-viscoelasticity behaviour of the composite of wood. Have been ignored of anisotropy in wood, and observation of the sample as homogenous, non-layered material, and also neglect of glue. We developed the constitutive relation including the impact of moisture, expressed through relaxation functions and given in integral form. The calculation results are compared with results of the experiment

This paper presents the analysis of the infl uence of conventional hot (CH) and high frequency (HF) gluing on relevant physical and mechanical properties of Laminated Veneer Lumber (LVL) made from beech peeled veneer with the thickness of 2.1 mm. Student’s T-test was applied to determine the signifi cance of differences between mean values of results obtained for the two different treatments. A signifi cant difference has been determined for the thickness loss, density, moisture and bending strength, while no statistically signifi cant difference has been established for the modulus of elasticity and shear strength of gluing between the means of the tested samples.
