Abstract [en]

A three dimensional finite element model has been used to analyse distortion in different laminated products of Norway spruce and Radiata pine such as laminated boards, panels and windows. The results show that twist of the products is strongly influenced by the radial variation in material data (spiral grain, shrinkage coefficients etc), original location of the separate pieces within the log and how they are oriented in the products. The results also indicate that the twist pattern for both the spices are quite similar but the twist values of Radiata pine are significantly higher because of its high spiral grain angle. The shape stability of laminated engineering products of wood can be much improved by combining the material knowledge and simulation technique to find the optimal choice and orientation of the individual pieces in the products.
