Exploration of seasonal moisture variation in standing loblolly and slash pine using time domain reflectometry

Autor: Robert B. White, Richard F. Daniels, Laurence R. Schimleck, Finto Antony

Publikováno v: European Journal of Wood and Wood Products. 77:1045-1052

Seasonal variation in the moisture content (MC) of standing trees can have a significant impact on wood (and when harvested) log weight; however, its variation is poorly understood owing to the destructive nature of sampling methodologies. To improve

Relationships between Static Mechanical Properties and SilviScan Measured Wood Properties in Loblolly Pine

Autor: Joseph Dahlen, Finto Antony, Richard F. Daniels, Laurence R. Schimleck

Publikováno v: Forest Products Journal. 68:37-42

Relationships between static bending modulus of elasticity (MOE) and SilviScan (SS) properties (SilviScan MOE [MOESS], specific gravity, and microfibril angle) were explored. Seventy-three clearwood specimens (25 by 25 by 406 mm) were cut from thirty

Acoustic evaluation of loblolly pine tree- and lumber-length logs allows for segregation of lumber modulus of elasticity, not for modulus of rupture

Loblolly pine ( Pinus taeda ) logs can be evaluated using acoustic velocity whereby threshold acoustic velocity values can be set to ensure lumber meets specified mechanical property design values for modulus of elasticity. There is a need to better
