Crushing Strength and Modulus of Elasticity of Unmachined Lodgepole Pine Stem Sections Compared to Machined Dowels of the Same Diameter–Kerfed and Kerf-Free, Round and Half-Round
Six-inch-long cylindrical or half-cylindrical stem sections from suppressed stands in two western Montana locations, tested when dry in compression, showed that specific gravity and two mechanical properties–maximum crushing strength parallel […]

Curvature-Stress Factor in Laminated Wood Beams
Pseudotsuga menziesii and Tabebuia pentaphylla were used to study th e influence of prestressing laminated curved members and to determine curvature-stress factors compared with straight nonprestressed laminated beams. Individual species […]

Cyanoacrylate Resins in Internal Bond Testing of Particleboard
Internal bond tests are rather long and, especially when accelerated aging is involved, glues are needed that couple quick setting properties with ability to adhere to wet surfaces. Cyanoacrylates meet […]

Cyclic Moisture Conditions and Their Effect on Strength and Stability of Structural Flakeboards
Durability of phenol-bonded particleboards under accelerated aging conditions has been a matter of concern for many years. This exploratory study outlines a series of cyclic accelerated exposures on laboratory-prepared flakeboards […]

Decay in Mine Timbers–Part III : Species-Independent Stress Grading
A pin-injecting Pilodyn and a James V-meter stress-wave measuring instrument were used to estimate crushing strength and modulus of elasticity (MOE) of mine props. Both nondestructive testing instruments can be […]
