Fracture toughness of wood based on experimental near-tip displacement fields and orthotropic theory
(Lincoln University. Applied Computing, Mathematics and Statistics Group, 1999-01)
Fracture toughness of New Zealand Pinus radiata in TL opening mode was determined from the displacement fields obtained from digital image correlation for about 400 data points within a 7x9 mm² area in front of the tip ...
Study of fracture properties of wood using high-speed video imaging and neural networks
(Lincoln University. Applied Computing, Mathematics and Statistics Group, 2002-04)
In this study, the Duration of Load (DOL) for crack initiation and propagation, crack speed, and load carrying capacity were investigated for three Rates of Loading (ROL) and four sizes of notched wood beams using high-speed ...
Nature of knot checks developed during seasoning of radiata pine sawn boards
(Lincoln University. Centre for Computing and Biometrics, 1996-10)
One hundred and sixty radiata pine boards were dried using different methods (air drying, commercial kiln drying and laboratory kiln drying) to study the effect of knot, wood and seasoning variables on the nature of knot ...
Modelling displacement fields of wood in compression loading using stochastic neural networks
(Modelling and Simulation Society of Australia and New Zealand Inc., 2007-12)
Most environmental and biological phenomena, such as underground water flow and pollution and properties of wood, exhibit variability which can not be successfully simulated using deterministic approaches because many ...
