STRUCTURAL STABILITY AND ENERGETICS OF AS, SB AND BI MICROCLUSTERS - EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTION CALCULATION
Katırcıoğlu, Şenay (Elsevier BV, 1991-08-09)
The structural stability and energetics of As, Sb and Bi microclusters having 3-7 atoms have been investigated by using a recently developed empirical many-body potential energy function (PEF), which comprises two- and three-body atomic interactions. The PEF satisfies both bulk cohesive energy per atom and bulk structural stability exactly. It has been found that the most stable structures of As3, Sb3 and Sb4 microclusters are in linear form with D-infinity-h symmetry, Bi7 is in hexagonal pyramid form with ...
Structural analysis of morphing control surfaces
Tıraş, Harun; Yaman, Yaman; Department of Aerospace Engineering (2017)
In this thesis, design and analysis of a hybrid trailing edge control surface is performed. Only camber motion and twisting motion of the trailing edge control surface are considered. There are four control surface configurations that are analyzed. For the first configuration, servo actuators actuating the control surface are inside the control surface volume and control surface is without pre-twist. For the second case, the control surface is pre-twisted and actuators are inside the control surface volume....
Structural Analysis of Synchronization in Networks of Linear Oscillators
Tuna, Sezai Emre (2022-07-01)
In undirected networks of identical linear oscillators coupled through dissipative and restorative connectors (e.g., pendulums undergoing small vibrations connected via dampers and springs), the relation between asymptotic synchronization and coupling structure is studied. Conditions on the interconnection under which synchronization can be achieved for some selection of coupling strengths are established. How to strengthen those conditions so that synchronization is guaranteed for all admissible parameter ...
STRUCTURAL STABILITY AND ENERGETICS OF C, SI, AND GE MICROCLUSTERS - EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTION CALCULATION
Erkoç, Şakir (Springer Science and Business Media LLC, 1991-01-01)
The structural stability and energetics of carbon, silicon, and germanium microclusters containing 3-7 atoms have been investigated by using a recently developed empirical many-body potential energy function (PEF), which comprises two- and three-body atomic interactions. The PEF satisfies both bulk cohesive energy per atom and bulk stability exactly. It has been found that the most stable C3-4 microclusters are linear with D-infinity-h symmetry but C5-7 microclusters are planar with D(nh) symmetry. Silic...
STRUCTURAL STABILITY AND ENERGETICS OF FCC METAL MICROCLUSTERS - EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTION CALCULATION
Erkoç, Şakir (Wiley, 1990-09-01)
The structural stability and energetics of microclusters containing 3 to 7 atoms of f.c.c. metal elements are investigated. A recently developed empirical many‐body potential function (PEF) is used in the calculations, which comprises two‐ and threebody atomic interactions. The PEF satisfies both, bulk cohesive energy and stability condition. It is found that the energetically most stable structures of microclusters are in compact form.
