On The Elastic Modulus of Wood斉藤, 昇
elastic modulusThe damping capacity and the elastic modulus are the most important parameters to characterize wood's mechanical properties. This paper deals with a simple experimental technique for determination of the wood damping factor by measuring the amplitude decrement of free vibrations in probes ...

ultrasonics, Goupia, Apuleia, wood, modulus of elasticity, Eucalyptus salignaKnowledge of the twelve elastic constants of wood—three moduli of elasticity ( E L , E R , and E T ), three shear moduli ( G LR , G LT , and G RT ), and six Poisson's ratios ( μ LR , μ RL , ...
7、Elastic modulus is an important mechanical characteristic of wood.弹性模量是木材的重要力学性质。 8、The yield strength and elastic modulus will decrease with the temperature increased.温度升高,原子热运动加强,屈服强度和弹性模量降低。 9、The stiffness of a structure will be subject to elastic modulu...
it was concluded that the common sub-micron particle elastic modulus was one fifth of the main direction.By analyzing the reasons for the increase of elastic modulus of medical molded plywood,other factors were also given,such as the size of wood shavings,density,glue amount,and gluing strength...
The cells are composed of the common wood constituents and their macroscopic elasticity is unusual: upon reversible bending to less than 50% of the clear-length the height to length ratio increases up to 10-fold. Such behaviour is not reflected by the reduced elastic modulus value from ...
In this work, the spatial variability of the transverse elastic modulus of clear spruce wood is quantified by conducting mechanical tests. Specimens of 120 mm nominal length with a small cross-sectional area were prepared and their quasi-static behavior was experimentally investigated under tensile ...
