This article presents investigations of self-positioning microstructures and nanostructures by analytical techniques, finite element analysis and atomic-scale modeling. Closed-form solutions for curvature radius of self-positioning hinge structures are obtained for plane strain and generalized plane strain deformation. The finite element method is used for predicting hinge curvature radius for ...

ab initio calculations were employed to investigate nitrogen inversion as a configuration change that can supply an infinitely useful switchable control mechanism for some complex systems. in this paper, design of a new artificial molecular nanohinge is discussed based on nitrogen inversion in which reciprocating motion of substituent in effect of inversion phenomenon, led to an open–close moti...

Coiled Carbon Nanotubes (CCNTs) are increasingly set to become a vital factor in the new generation of nanodevices and energy-absorbing materials due their outstanding properties. In following work, multi-objective optimization CCNTs is applied regarding mechanical performances. Apart from finding best trade-off between conflicting properties (e.g. yield stress strain), enables us find astonish...
