Prediction of Young’s Modulus of Perfect and Defective SWCNTs with Various Loading Methods
In this paper, the influence of various vacancy and Stone-Wales defects on the Young’s modulus of single walled carbon nanotubes is investigated via a structural model. Dispersion in experimental results is the motivation for this work. Our results...
Empirical relations between strength and static and dynamic elastic properties of Asmari and Sarvak limestones, two main oil reservoirs in Iran
, information on the value of UCS and ES along the well length is often discontinuous and limited to cross well with the core. Therefore, dynamic Young’s modulus (Ed) determined from open hole log data such as density (ρ) and compressional and shear wave...
Effect of external strain on electronic structure of stanene
molecular mechanic models are used to estimate the Young’s modulus of stanene. According to our calculations we estimate the in-plane stiffness of stanene Ys = 40 N/m. By matching DFT and molecular mechanic results of stanene, we investigate the size...
Effect of Temperature on Young's Modulus of Graphene
of this work is to present
a density functional study to predict the temperature variation of Young’s modulus of
graphene. To this end, the energies of phonons as well as thermodynamic functions
are calculated from phonon calculations via...
Effect of defects and loading on prediction of Young’s modulus of SWCNTs

Estimation of the Young’s modulus of single-walled carbon nanotubes under electric field using tight-binding method
In this paper, the Young’s modulus of single-walled carbon nanotubes
(SWCNTs) under uniaxial strain is studied by using the
tight-binding method in the nearest neighbor approximation while
the curvature effect take into account...
Mechanical Unfolding of Titin I27 Domain: Nanoscale Simulation of Mechanical Properties Based on Virial Theorem via Steered Molecular Dynamics Technique
results are investigated. Due to different viewpoints on
the Virial stress definition, the role of the kinetic stress in the Virial stress definition is
elucidated. The obtained Young’s modulus is about GPa. It is found that the ultimate...
