    • The relationship between bending and tension strength of Irish and UK spruce and pine 

      Gil-Moreno, David; Ridley-Ellis, Dan; O’Ceallaigh, Conan; Harte, Annette M. (Springer, 2022-02-07)
      The correct characterisation of wood properties is fundamental for the best utilisation of resources. In Europe, grading is defined by strength classes that are determined based on either bending or tension tests. The ...
    • Strength grading of timber in the UK and Ireland in 2021 

      Ridley-Ellis, Dan; Gil-Moreno, David; Harte, Annette M. (Taylor & Francis, 2022-03-19)
      This paper summarises the state of the art for strength grading of construction timber grown in the United Kingdom and the Republic of Ireland. It includes the latest approvals based on recent research on spruce, larch and ...
    • 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 ...
    • Timber grading potential of Douglas fir in the Republic of Ireland and the UK 

      Gil-Moreno, David; Ridley-Ellis, Dan; Harte, Annette M. (Taylor & Francis, 2019-05-19)
      Results of the recently approved machine control grading settings for Douglas fir in the Republic of Ireland and the UK have shown that the species can be graded to C18, and higher strength classes, and while there is a ...
    • 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 ...
