The modulus of elasticity Youngs modulus E is a material property, that. From the Hooks law the modulus of elasticity is defined as the ratio of the stress to.modulus of elasticity of the cultured SC cells examined in this study, in central, non-nuclear regions, ranged between. Johnson B.all require an effective E, the Youngs modulus or elastic modulus, to quantify. Elastic moduli, such as the ...

a closed form three-dimensional solution is presented for determination of the local buckling (cell buckling) load of the nanosheets. moreover, an expression is proposed for the effective 2d young’s modulus of the unit cell of the nanosheet. in this regard, a three-dimensional efficient space-frame-like geometrical model with angular and extensional compliances is considered to investigate stab...

Deformation modulus of rock mass has a significant role in the support design of an underground excavation. It is determined by expensive in-situ tests or by empirical models. Existing models for estimation of deformation modulus do not consider its stress dependence. Herein, data from several sources is used to develop a stress- (depth-) dependent relation for estimation of deformation modulus...

Cellulose-based materials draw their good mechanical properties from the cellulose crystal. Improved understanding of crystal properties could lead to a wider range of applications for cellulose-based materials, Cellulose crystals show high axial Youngs modulus. Cellulose can attain several allomorphic forms which show unique structural arrangements in terms of both intra-molecular and intermol...

Investigation mechanical hardness, elastic anisotropy, optical properties, dynamical stability thermal properties are considered for time. The estimated values stiffness constants moduli found in good agreement with available results. micro ...

Single wall nanotubes have been demonstrated to have remarkable physical properties: Youngs Modulus of >ITPa; breaking strength of 100 G ~ and metallic conductivity. The most perfect examples of them have been produce~ via laser ablation or arc-discharge processes [1,2]. These processes are characterized by theft low productivity, of the order of grams per day per unit, and they are generally a...

Very recently, the two-dimensional (2D) form of MoSi2N4 has been successfully fabricated [Hong et al., Sci. 369, 670 (2020)]. Motivated by theses recent experimental results, herein we investigate structural, mechanical, thermal, electronic, optical and photocatalytic properties using hybrid density functional theory (HSE06-DFT). Phonon band dispersion calculations reveal dynamical stability mo...

Electrical energy storage devices are crucial for and distribution purposes. MXene (MX), a 2D material, conductive organic polymers, such as polypyrrole (PPy), have been widely used electrode material in electronic devices. This work calculated the elastic modulus electrical conductivity of MX/PPy nanocomposite using finite element model. Response Surface Methodology (RSM) was to optimize respo...

One of the efficient techniques to improve the behavior of the paved road under traffic loads is implementing the geosynthetic material in the sub-base or the soil under the road. In the past years, many researches have been done about this topic, but the study on the effect of soil/load conditions on the performance of the rehabilitated paved road by geogrid in order to investigate the effecti...
