Characterization of the Strength of Juvenile Wood of Loblolly Pine (Pinus Taeda L.)
The specific gravity, flexural properties, and longitudinal shrinkage of juvenile wood, i.e., wood from within about 10 growth rings of the pith, and of mature wood were determined from a […]

Circular Saw Stiffness as a Measure of Tension
The tensioning of circular saw blades is the most common method of increasing their stability. Tensioning induces favorable residual stresses, which increase the saw stiffness in specific bending modes. It […]

Column Strength of Parallel Laminated Veneer and Plywood
Parallel laminated wood veneers (PLV) are now being glued into structural boards, plants, and studs. Compressive and buckling strength tests have shown that plywood is about half as strong, in […]

Comparative Properties of Douglas-Fir Boards Made from Parallel-Laminated Veneers vs. Solid Wood
Static bending and cleavage resistance of nominal 1-by 6-inch boards made from five and seven parallel plies of rotary-cut Douglas-fir veneer compared favorably with that of clear, vertical-grain, solid-sawn Douglas-fir […]

Comparison of grade, yield, and mechanical properties of lumber produced from young fast-grown and older slow-grown planted slash pine
Twenty-five 20-year-old, fast-grown slash pine test trees and twenty-five 50-year-old slash pine control trees of similar diameter at breast height were processed through the Temple-Inland Forest Products Co. (formerly Temple […]

Comparison of Kiln Schedules for Drying Spruce
Eighteen charges of nominal 2-inch spruce [Picea glauca (Moench) Voss and Picea engelmannii Parry] from the British Columbia Interior were dried using six temperature-classification schedules: conventional, low-high, low-variable high, constant […]

Comparison of Mechanical Properties of Non-Load-Bearing Panels in Walls
The mechanical barrier function of non-load-bearing panels or partitions is analysed as a basis for a comparison of panels. A certain mechanical solidity and rigidity, expressed as bending stiffness, is […]

Comparison of Moisture Content Distribution, Stress Distribution, and Shrinkage of Red Oak Lumber Dried By a Radio-Frequency/Vacuum Drying Process and a Conventional Kiln
End-matched samples of 8/4 red oak, 8 feet long, were dried in a radio-frequency/vacuum (RFV) kiln and a conventional kiln to compare the moisture content distribution, stress distribution, and shrinkage […]

Comparison of Results from Standard 2-Inch with 1-1/2-Inch Shear Block Tests
Radial and tangential shear and shear at 45? to the annual rings of southern pine were evaluated using the standard 2- by 2-inch shear block and experimental 2- by 1-1/2-inch […]

Comparison of Standard Block Shear Test with the Panel Shear Test
The ASTM standard shear test for small, clear specimens of wood, developed about 1910, does not subject the specimen to uniformly distributed pure shear. This inadequacy applies in the elastic […]

Comparison of the Properties of Heat and Radiation Cured Wood-Polymer Combinations
Comparisons were made between certain physical and mechanical properties of Betula lutea Michx. f. polymerized with methyl methacrylate “in-situ” by gamma irradiation and by heat. Betula lutea was used because […]

Component Variables on Properties of Particleboard for Exterior Use
This study of exterior-type particleboard was designed to evaluate the influence of the major component variables and end-use properties. A “standard” 40 lb./cu.ft. Douglas-fir flakeboard was manufactured, containing 6 percent […]

Compression Strength Adjustments for Moisture in Commercial Douglas-Fir Plywood
The Madison formula for adjusting values for compression stress in commercial plywood consistently overestimates the reduction in strength from low to high moisture contents. This is not surprising since the […]

Compressive Strength of Cylindrical Samples as An Indicator of Wood-Cement Compatibility
Compatibility of wood-cement mixtures proposed by early studies was expressed as an inhibitory index, which was derived from hydration temperature and/or hydration time. Sometimes this index does not reflect the […]

Compressive Strength of One- and Two-Ply Laminated Timbers
Two-ply laminated timbers were significantly stronger than single-ply lumber in both average and near-minimum compressive strength. Average stiffnesses of one- and two-ply timbers were essentially equal. Results suggest that present […]
