Effects of Thermal Modification on the Flexure Properties, Fracture Energy, and Hardness of Western Hemlock [PDF]
arXiv, 2023 This study investigates the effect of thermal modification on the flexural properties, transverse fracture energy, and hardness of western hemlock, a material which is finding increasing applications in construction. Flexure tests on specimens featuring longitudinal and transverse grains showed that thermal modification at 167C slightly improves the ...

Flexures for Kibble balances: Minimizing the effects of anelastic relaxation [PDF]
Metrologia 61 045006 (2024)We studied the anelastic aftereffect of a flexure being used in a Kibble balance, where the flexure is subjected to a large excursion in velocity mode after which a high-precision force comparison is performed. We investigated the effect of a constant and a sinusoidal excursion on the force comparison.

Flexural modulus identification of thin polymer sheets
IOP Conference Series: Materials Science and Engineering, 2011 The method of determination of the flexural Young's modulus is based on a solution to the problem of compression of a thin-walled cylindrical specimen by two parallel planes (TWCS method). This method was employed to calculate the flexural modulus for PET polymer compositions.

Stretching and buckling of small elastic fibers in turbulence [PDF]
Phys. Rev. Lett. 121, 154501 (2018), 2018 Small flexible fibers in a turbulent flow are found to be most of the time as straight as stiff rods. This is due to the cooperative action of flexural rigidity and fluid stretching. However, fibers might bend and buckle when they tumble and experience a strong-enough local compressive shear.

Effect of infill pattern and build orientation on mechanical properties of FDM printed parts: An experimental modal analysis approach [PDF]
arXiv, 2022 Fused Deposition Modeling (FDM) is one of the most widely explored additive manufacturing method that uses thermoplastic materials to manufacture products. Mechanical properties of parts manufactured using FDM are influenced by different process parameters involved during manufacturing as they impact the bonding among different layers of cross-section.
