TL;DR: Multiwalled carbon nanotubes with a mean fracture strength >100 GPa are reported, which exceeds earlier observations by a factor of approximately three and are in excellent agreement with quantum-mechanical estimates for nanot tubes containing only an occasional vacancy defect, and are approximately 80% of the values expected for defect-free tubes.

TL;DR: The computational results demonstrate similar size dependence, complementing the experimental findings, and reveal that the observed size effect is an outcome of surface reconstruction together with long-range ionic interactions.

TL;DR: In this paper, the size effects on free-standing polycrystalline FCC thin films subjected to macroscopic homogeneous axial deformation have been investigated and it was shown that thickness plays a major role in deformation behavior and fracture.

TL;DR: Molecular dynamic simulations, using the Buckingham potential, were used to examine failure mechanisms in nanowires with diameters up to 20 nm and revealed a stress-induced phase transformation from wurtzite phase to a body-centered tetragonal phase at approximately 6% strain.

TL;DR: In this article, an analytical model based on the energy method in both small deformation and finite kinematics (large deformation) regimes is used to interpret the measurements of the deflection of the cantilever under electrostatic actuation.
