A relationship between wave dispersion and fracture strength for a composite material

Creator:: Ilcewicz, Larry Bert
Abstract:: Wave dispersion and fracture are phenomena that involve. mechanisms triggered at the scale of a material's internal structure. Experiments were performed with a candidate material to judge the hypothesis that wave dispersion measurements can be used to nondestructively predict fracture strength. Wood-based particleboard was chosen as the candidate material because...

Analyzing manufacturing system changes using discrete event simulation

Creator:: Baker, Eric S.
Abstract:: This research studied the effects of changing from a traditional manufacturing system to a cell manufacturing system in a value-added wood products company. Discrete event simulation was used to describe the current system and the proposed new systems. Parts were separated into part families that shared similar processing requirements. From...

Simulating changing diameter distributions in a softwood sawmill

Creator:: Salichon, Maxence C.
Abstract:: Sawmills are very complex systems that involve many manufacturing processes. The variability of their raw material adds further to this complexity as each log has characteristics that determine its processing path. Therefore, computer simulation is a very useful technique for analyzing sawmill performance. This thesis describes a simulation computer model...

The fracture toughness of medium density fiberboard and other fiber bridging composites

Creator:: Matsumoto, Noah T.
Abstract:: In many composites, fiber bridging develops as part of the fracture process. Fiber bridging invalidates many toughness evaluation methods such as the ASTM E399 and complicates the identification of crack length, which is a necessary parameter in energy methods. In order to measure the toughness of fiber bridging composites, an...

Modelling root reinforcement in shallow forest soils

Creator:: Skaugset, Arne E.
Abstract:: A hypothesis used to explain the relationship between timber harvesting and landslides is that tree roots add mechanical support to soil, thus increasing soil strength. Upon harvest, the tree roots decay which reduces soil strength and increases the risk of management -induced landslides. The technical literature does not adequately support...

Using discrete-event simulation to study the influence of log yard sorting on sawmill processing efficiency of small-diameter timber

Creator:: Pinon, Olivia J.
Abstract:: A sawmill is similar to other manufacturing enterprises when it comes to making decisions, scheduling production and meeting customer demands. In order to help sawmills achieve their goals, and because there is such a high degree of variability in the raw material used in this industry, computer simulation has proven...

Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

Creator:: Sharp, Christopher J.
Abstract:: Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...

Experimental and finite-element analysis of stress distributions near the end of reinforcement in partially reinforced glulam

Creator:: Kirlin, Chad P.
Abstract:: Recently, fiber-reinforced plastics (FRP lamina) have been applied to glued-laminated (glulam) timber for the purpose of improving bending strength and stiffness. Initially, full length reinforcement using FRP lamina was developed. However, the cost of FRP lamina is a significant portion of the total cost of reinforced glulam. Therefore, it is...

Transient conduction with counter mass flow in wood

Creator:: Pfeiffer, Nikolaus, 1960-
Abstract:: This paper deals with the thermal decompositon of wood slabs under fire conditions. The partial differential equation is solved numerically by the use of an implicit finite difference method. Wood is treated as two components, Lignin and Hemicellulose on one side, and Cellulose on the other side. The chemical reactions...
