1988. Flexural stiffness and modulus of elasticity of flower stalks from Allium sativum as measured by multiple resonance frequency spectra. Am. J. Bot., 75: 1517-1525.NIKLAS K J, MOON F C. Flexural stiffness and modulus of elasticity of flower stalks from Allium sativum as meas- ured ...
As previously discussed in Chapter 1, the term modulus of elasticity (elastic modulus) refers to the elastic stiffness of a material, and the term hardness refers to the resistance to permanent indentation. Both mechanical properties are highly important characteristics, along with surface roughness, ...
Vessel wall compliance is dependent on the status of two major scaffolding proteins: collagen and elastin5. Normally, there is a tightly regulated balance between synthesis and degradation of these two proteins. Anomalies occur in this regulatory system such as that which accrues from inflammatory ch...
Stiffness depends on the modulus of elasticity, also known as Young’s Modulus. While strength can vary from grade to grade, Young’s Modulus is constant for any given metal and is independent of external stressors such as heat treatment, processing, or cold work. In simple terms, when it...
The tensile stiffness can be converted to Young's modulus, E, the modulus of elasticity, by dividing by the thickness t(m): (6.20)E=Si/t (h) Secant modulus: This is the slope of the line drawn from the origin of the stress–strain curve to a point of interest on the curve. In ...
Aortic extension was calibrated using an optical camera to obtain photographs at different stretches, providing calibration of the upper hook and allowing vessel diameters during systole and diastole to be calculated. Subsequently, the Peterson pressure-strain modulus of elasticity (Ep) was calculated ...
In Eq. (58), (58) C1111 = ∂ S11 ∂ E11 = ∂ 2 ϕ¯ ∂ E121 (59) is the component of the material elasticity tensor in the bar axial direction or, in other words, the tangent elastic modulus of the material. More explicit expressions of Eqs. (57) and (58) can be...
aStiffness caused by errors of elements is the modulus of elasticity of concrete change on the one hand, on the other hand section size changes, all affect the stiffness. For symmetrical cantilever construction of continuous girder bridge, and improved overall stiffness, pouring concrete in the cou...
aThe stiffness of a structural system and, in particular a framed structure, is directly proportional to the modulus of elasticity E and the size of the cross-sections of the structural elements 一个结构系统的僵硬和,特别是一个被构筑的结构,与弹性模量直接地是比例E和结构元素的横断面的大小[translate...
One of the most important terms in implant technology is stiffness. Stiffness is a material property that is determined by the resistance of an elastic body to deflection or deformation by an applied force. This is expressed as Young’smodulus of elasticity,E, which is the ratio of the rate...
