The experimental and model results for these second generation LASMP formulations are then compared with earlier LASMP generations (detailed previously in Beblo and Mauck Weiland, 2009, “Light...

..., the developed inversion algorithms are capable of estimating richer properties of the medium. That is, not only Young’s modulus of elasticity but also layer thickness, number of layers, and other information could be inferred from the measurement. Specifically, in this study, we first use the forward...

... thickness t . In the present work, the wall thickness of a CNT is taken to be 0.335 nm. As discussed in Ref. 1 , this value of the thickness, together with the value of D (in Eq. 19 ), yields the Young modulus Y of a SWNT to be 1.08 TPa. The usually accepted value of Y for CNTs...

..., a membrane with uniformly distributed load around an inner circumference is studied. For all the calculations shown in the following figures, Young’s modulus, the outer radius, and the thickness of the membrane of 1 are assumed. This is equivalent to nondimensionalizing the stresses σ ¯ = ( σ...

This work discusses in situ characterization strategies currently being implemented as well as the current and projected performance of LASMPs. While for the current state of the art...

... boundary conditions in the analyses of SWCNTs and their ECSs. It is found that the wall thickness of the ECS (and hence of a SWCNT) is ∼ 1 Å and Young’s modulus of the material of the ECS (and hence of the SWCNT) is ∼ 3.3 TPa . Both quantities are independent of the helicity and the diameter of the SWCNT...

... is found equal to 1 ∕ 4 so that there is only one independent elastic constant—Young’s modulus. Such restriction is not suitable for many materials. In this paper, we propose a modified VIB (MVIB) formulation, which allows for two independent linear elastic constants. It is also argued that the discrepancy...
