DendroLight is a novel wood material primarily used as core material for furniture industry. The manufacturing of this material was started at the year 2010 in Ventspils. It is made from profiled/perforate wood boards stacked in perpendicular layers and then sliced once more in plates perpendicularly to the board’s layers. The main advantage of such a solution is significant reduction of structural weight (up to 40 %) comparing to conventional timber. Material properties are not fully assessed jet, however first experimental test runs demonstrate that it has sufficient stiffness for the use as core material in wood sandwich panels in load bearing structures like walls and floors[1]. For further development of load bearing structures with DendroLight core, reliable design methodology is needed, able to assess detailed geometry component (like profiled board web thickness) influence over the stiffness for large scale structure. In current research several numerical modeling techniques have been compared including numerical models from shell and solid elements in ANSYS and ABAQUS software. The aim is to elaborate an accurate numerical model for prediction of DendroLight structure mechanical behavior. Precision of numerical model is estimated comparing displacements of experimentally tested small scale specimens in compression and bending with mechanical responses of numerical model.
