The chiral lattice is a unique structural network not symmetric to its mirror image, and with a negative Poisson’s ratio. Previous investigations have considered this structural network for the design of superior structural components with sandwich construction, but these were limited by the in-plane Poisson’s ratio predicted to be exactly −1. This paper presents estimates of the mechanical pro...

Double-layer quantum Hall systems possess interlayer phase coherence at sufficiently small layer separations, even without interlayer tunneling. When interlayer tunneling is present, application of a sufficiently strong in-plane magnetic field B i.Bc drives a commensurate-incommensurate ~CI! transition to an incommensurate soliton-lattice ~SL! state. We calculate the Hartree-Fock ground-state e...

Carbon nanotubes (CNTs) demonstrate unusually high stiffness, strength and resilience, and are therefore an ideal reinforcing material for nanocomposites. However, much work has to be done before the potentials of CNT-based composites can be fully realized.  Evaluating the effective material properties of such nanoscale materials is a very difficult tasks.  Simulations using molecular dynamics ...

In this paper, the free vibration analysis of moderately thick rectangular plates axially moving with constant velocity and subjected to uniform in-plane loads is investigated by the spectral finite element method. Two parallel edges of the plate are assumed to be simply supported and the remaining edges have any arbitrary boundary conditions. Using Hamilton’s principle, three equations of moti...

Abstract Light-gauge steel framed (LSF) wall systems of low- and mid-rise buildings are made cold-formed studs tracks lined with sheathing material such as gypsum plasterboard. The stiffness provided by can be idealised into three main components, namely, in-plane, out-of-plane rotational stiffness. Idealised in-plane has been used commonly in the numerical analytical studies stud walls. Experi...

The established soft pneumatic grippers have the benefit of flexible and compliant gripping, but they cannot withstand lateral loads, due to low stiffness material. This paper proposes an endoskeleton gripper. action finger is performed by air chambers, gripping force transferred rigid within finger. in similar a wristwatch chain; hinge mechanism permits relative rotation working plane restrict...
