Stress Analysis and Prediction in 3-Layer Laminated Veneer Lumber: Response to Crack and Grain Angle
Keywords:Tensile strength, laminated veneer lumber, crack, sloping grain
AbstractA mathematical model has been developed that can predict the elastic properties in tension of 3-layer laminated veneer lumber with clear, straight-grained outer layers and an inner layer with sloping grain and a crack parallel to that grain. This analysis provides a theoretical means of determining the tension behavior of the material containing a crack at any angle to the direction of the stress and takes into account the orientation and basic properties of the individual orthotropic layers.
