Performance study on mounting system for displacement transducer in mechanical tests of timber samples using photogrammetry method (2021)
Journal Article
Mohamed, A., Zhang, H., Deng, Y., Lehmann, M., Sigrist, C., Uheida, K., Zheng, Y., Bahadori-Jahromi, A., Shahidan, S., & Caudoux, R. (2022). Performance study on mounting system for displacement transducer in mechanical tests of timber samples using photo

This paper presents a unique study to reveal the effect of the mounting system of the linear variable differential transformer (LVDT) on the mechanical property tests of timber materials. This effect has been overlooked in the past but proven to be s...

Determining equivalent-sectional shear modulus in torsion tests for laminated glass beams using photogrammetry method (2021)
Journal Article
Uheida, K., Deng, Y., Zhang, H., Galuppi, L., Gao, J., Li, X., Huang, S., Qin, X., Wong, S. H. F., Guo, J., Zhang, G., & Mohamed, A. (2021). Determining equivalent-sectional shear modulus in torsion tests for laminated glass beams using photogrammetry met

This paper proposes a concise concept for quantifying the shear/torsional stiffness of the laminated glass beams experimentally by introducing the Equivalent-Sectional Shear Modulus (ESSM), that is directly measured from the torque and sectional-rota...

Applicability of the Torsion Test and Photogrammetric Approach on Structural Timber Beams (2021)
Journal Article
Mohamed, A., Uheida, K., Quan, Y., & Zhang, H. (2021). Applicability of the Torsion Test and Photogrammetric Approach on Structural Timber Beams. International Wood Products Journal, 12(3), 206-217. https://doi.org/10.1080/20426445.2021.1952047

The torsion test is recommended as a standard approach to determine the shear modulus of structural-size timber and glulam beams. However, there is a difficulty in measuring the rotational deformations of timber joists. A stereo camera system and pho...
