In this paper in the Journal of the Mechanics and Physics of Solids (vol. 84, p. 358,
http://authors.elsevier.com/a/1Rk5057Zjdx-o ) we propose a
new theory for the mechanical properties of fivefold twinned nanowires.
We show that the Frank vector of the central wedge disclination depends on the uniaxial strain,

This paper reports the quantitative measurement of a full spectrum of mechanical properties of fivefold twinned silver (Ag) nanowires (NWs), including Young’s modulus, yield strength, and ultimate tensile strength. In-situ tensile testing of Ag NWs with diameters between 34 and 130 nm was carried out inside a scanning electron microscope (SEM). Young’s modulus, yield strength, and ultimate tensile strength all increased as the NW diameter decreased.
An excellent student with research expertise and interest in molecular dynamics simulation and theory of mechanical and/or thermal transport properties in nanomaterials such as nanowires, bulk nanotwinned metals and graphene, is sought to fill a new PhD opening in my group starting in Fall 2012. Interested students should send me a detailed CV with a description of past research achievements and the names of references to frederic.sansoz [at] uvm.edu.
