Nanoindentation of a circular sheet of bilayer graphene
, 2010 Nanoindentation of bilayer graphene is studied using molecular dynamics simulations. We compared our simulation results with those from elasticity theory as based on the nonlinear F\"{o}ppl-Hencky equations with rigid boundary condition.

Using DMA to Simultaneously Acquire Young's Relaxation Modulus and Time-dependent Poisson's Ratio of a Viscoelastic Material [PDF]
, 2014 A method to obtain the Young's relaxation modulus and time-dependent Poisson's ratio simultaneously by using DMA is developed with the assumption of constant bulk modulus instead of constant Poisson's ratio.

Investigation of the Elastic Properties of Graphenylene Using Molecular Dynamics Simulations [PDF]
Materials Research, 2016 Molecular dynamics simulations are used here to study the mechanical behavior of graphenylene under uni-directional and bi-directional loadings. The effects of nanosheet chirality and size on Young's modulus of graphenylene are investigated.

Size, vacancy and temperature effects on Young's modulus of silicene nanoribbons [PDF]
RSC Adv., 2015, 5, 96052, 2015 We report results on the Young's modulus (YM) of defect-free and defective silicene nanoribbons (SNRs) as a function of length and temperature. In this study, we perform molecular dynamics simulations using the Environment-Dependent Interatomic Potential (EDIP) to describe the interaction of the Si atoms.

Effect of local anisotropy on fatigue crack initiation in a coarse grained nickel-base superalloy
, 2018 In the present work, theoretical approaches, based on grain orientation dependent Young's modulus and Schmid factor are used to describe the influence of local grain orientation on crack initiation behaviour of the coarse grained nickel base superalloy ...

Development of a new correlation to determine the static Young’s modulus
Journal of Petroleum Exploration and Production Technology, 2018 The estimation of the in situ stresses is very crucial in oil and gas industry applications. Prior knowledge of the in situ stresses is essential in the design of hydraulic fracturing operations in conventional and unconventional reservoirs. The fracture

Determination of Young’s Modulus of Ultrathin Nanomaterials
Nano Letters, 2015 Determination of the elastic modulus of nanostructures with sizes at several nm range is a challenge. In this study, we designed an experiment to measure the elastic modulus of amorphous Al2O3 films with thicknesses varying between 2 and 25 nm. The amorphous Al2O3 was in the form of a shell, wrapped around GaAs nanowires, thereby forming an effective ...
