Large span cable-supported structures have been developed rapidly in China, and they always adopt high-strength steel cables as structural members. However, the modulus of elasticity and yield strength of steel material will decrease seriously under fire conditions while fire protection is unlikely to...
0 = efficiency factor of reinforcement in the loading direction a c = cross section area of ferrocement composite section a = depth of the compression block in the ferrocement matrix b = width of the specimen c = neutral axis depth from the top of the specimen e s = modulus of elasticity...
Moreover, wind and MOR are not the only factors to take into account: for self-loading and the elastic stability (i.e. buckling) of plant stems, solutions were proposed by Ref.24 and e.g.25 in which the Modulus Of Elasticity (MOE) is a determining factor. Greenhill's proposal was ...
Several models for the Young′s modulus of filler-reinforced rubber were evaluated.The modified Einstein-Smallwood model was only good at low filler concentrations, and the modified Haplin-Tsai equation could predict the modulus of filled elastomers at higher volume fractions.The four models for desc...
A solid unit is used to simulate the switch rail, with a material density of 7850 kg/m3, modulus of elasticity of 2.1 × 1011 Pa, and Poisson’s ratio of 0.3 [28,29,30]. The influence of the variable cross-section of the switch rail is considered, and each characteristic section of...
In the above equation, G is the fractal roughness and E* is the equivalent Young’s modulus. 2.3.4. Critical Truncation Area Model For a certain micro-convex body with a truncation area equal to the critical truncation area sc, the contact type changes from an ideal plastic contact state ...
Young´s modulus of elasticity of the i-th group of reinforcement resisting torsion εsw,T . . strain in the reinforcement due to torsion The resulting stress in each stirrup due to applied torsion is calculated as: σsw,i,T=εsw,T⋅Esi,T{{\sigma }_{sw,i,T}}={{\varepsilon }...
The present paper is concerned with the free vibration analysis of double-walled carbon nanotubes embedded in an elastic medium and based on Eringen's nonlocal elasticity theory. The effects of the transverse shear deformation and rotary inertia are included according to the Timoshenko beam theory....
Based on the analyses and experimental data, new equations for the modulus of elasticity of thin cement composite are proposed. It is observed that the flexural modulus of elasticity of thin cement composite depends on the elastic modulus of mortar and some factor of the difference of elastic ...
ModulusofElasticityPitchcirclediameterSurface densification provides the opportunity for manufacturing technology to advance into the manufacture of highly stressed product groups such as automotive transmission gears. A key durability design requirement for such applications is the determination of allowable ...
