Special Issue Information

Dear Colleagues,

The use of wood is continuously growing in different markets. Presently, it is possible to observe a worldwide movement to increase its use in the construction sector, the idea being to tackle climate change through renewable resources. Also, the increased use of new technologies allows for the use of underutilized species within the production of wood products, with special emphasis on fast-growing species.

The aim of this Special Issue is to promote and disseminate the most recent advances in the study of the mechanical properties of wood and wood products (e.g., sawn wood, engineered wood products, plywood, wood panels, among other products) for structural and non-structural applications. Moreover, this Special Issue will focus on new advances in grading processes based on the use of non-destructive methodologies and/or experimental characterization of wood products, and the definition of mechanical properties from underutilized and emerging species, as a way to increase the range of species suitable for engineered wood products.

We encourage authors to submit manuscripts containing scientific findings in the field of grading timber, experimental and numerical characterization of wood products, and review papers. Results related to the potential of underutilized species are welcome.

The static bending properties of Scots pine (Pinus sylvestris L.) clear wood were studied using a material collected from commercial thinning forests in eastern Finland. In Myrtillus type, the modulus of elasticity and bending strength of the first thinning wood were 7.8 GPa and 66.0 MPa, respectively, whereas for more mature wood from the second thinnings, the modulus of elasticity and bending strength were 10.0 GPa and 80.3 MPa. The results were compared with final fellings, which resulted in the modulus of elasticity of 10.1 GPa and bending strength of 81.8 MPa. The bending properties of the first thinning material were low, and thus they did not indicate any potential for applications requiring high strength or stiffness and material homogeneity. On the contrary, the properties of Scots pine wood from the second commercial thinnings may be comparable with or sometimes even better than those of the final-felling wood. The results can be utilised in wood marketing, procurement, sorting, allocation to different industries and end-uses, as well as in wood processing, product sales, and branding. Full article

A new method for the determination of the dynamic modulus of elasticity (Ed) of pine wood, based on the transverse vibration excitation and electromechanical impedance (EMI) response of the lead zirconate titanate (PZT) transducer is proposed. The influence of the length to thickness ratio of the pine specimen on the measurement accuracy was studied through modal simulation analysis. Based on the results of the modal simulation, the size of the pine specimen was optimized, and the scanning frequency range of the EMI response was determined. On this basis, the EMI simulation and test of the pine specimen coupled with a PZT patch were carried out to verify the effectiveness of the novel method. The impedance simulation results of three kinds of pine specimens show that a unique and significant formant appears in the real part of each EMI response curve, and the maximum relative errors of the rectangular PZT patch and circular PZT patch are 1.34% and 1.81%, respectively. The impedance test results of three kinds of pine specimens indicate that the maximum relative errors of the rectangular PZT patch and circular PZT patch are 1.41% and 1.68%, respectively, compared with the corresponding results obtained by the traditional transverse vibration method. Simulation and experimental results verify the validity of the proposed method for the elastic modulus determination of pine wood. Full article
