Test machine effect in the determination of modulus of elasticity for strength graded timber
Gil-Moreno, David; Ridley-Ellis, Dan; Harte, Annette M. (World Conference on Timber Engineering (WCTE2021), 2021-08-09)This paper investigates if the relationship between the global and local moduli of elasticity (MoE), measured in bending tests, is affected by the test machines employed, and how that may influence strength grading. The ... -
Use of nondestructive techniques for determination of tension parallel-to-grain properties of spruce
Gil-Moreno, David; O'Ceallaigh, Conan; Ridley-Ellis, Dan; Harte, Annette M. (USDA Forest Service Forest Products Laboratory (FPL), 2019-09-25)The paper presents a study of the tension properties of Irish-grown Sitka spruce. Fifty timber pieces were destructively tested having resonant frequency and knots measured. The aim was to improve knowledge of the performance ...
