Numerical Analysis Viscoelasticity Properties Composite of Wood
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
