We investigate the structure of the solution of the Reissner–Mindlin plate equations in its dependence on the plate thickness in the cases of soft and hard clamped, soft and hard simply supported, and traction free boundary conditions. For the transverse displacement, rotation, and shear stress, we develop asymptotic expansions in powers of the plate thickness. These expansions are uniform up t...

In the present article, generalized thermoelastic wave model with and without energy dissipation under fractional time derivative is used to study physical field in porous two-dimensional media. By applying Fourier-Laplace transforms eigenvalues scheme, quantities are presented analytically. The surface shocked by heating (pulsed heat flow problem) application of free traction on its outer (mec...

A new mathematical model of the transport of mucus and periciliary liquid (PCL) in the airways by cilia is presented. Mucus is represented by a linearly viscoelastic fluid, the mat of cilia is modelled as an 'active porous medium.' The propulsive effect of the cilia is modelled by a time-dependent force acting in a shear-thinned 'traction layer' between the mucus and the PCL. The effects of sur...

Conservation tillage is an energy efficient and low cost tillage system to improve soil environment compared with conventional tillage systems. However, the rice residue management becomes an "impossible to achieve" task due to high soil moisture content at harvest time and the thickness of rice straw. Disc type furrow openers are used for both seed drilling as well as straw cutting during no t...

Nano-particles consisting of a core surrounded by multiple outer shells (multishell particles) are used as novel functional materials as well as stiffeners/toughners in conventional composites and nanocomposites. In these heterogeneous particles, the mismatch of thermal expansion coefficients and lattice constants between neighboring shells induces stress/strain fields in the core and shells, w...

BACKGROUND This paper examines the extent to which actors from sectors other than health engaged with the South Australian Health in All Policies (HiAP) initiative, determines why they were prepared to do so and explains the mechanisms by which successful engagement happened. This examination applies theories of policy development and implementation. METHODS The paper draws on a five year stu...

The motion of a uid subject to Navier{Stokes equations with Coriolis force, to a Robin type traction condition at the surface and to a friction condition at the bottom is investigated. An asymptotic model is derived as the aspect ratio = depth/width of the domain go to 0. When Reynolds number is not too large, this is mathematically justiied and the 3D limit velocity is given in terms of wind, ...

A pneumatically-driven robot traverses surfaces with different traction by adopting an undulatory mode of locomotion. The robot is composed of soft elastomer (elastic modulus ∼100 kPa), an inextensible but flexible neutral plane, and embedded pneumatic channels. In contrast to conventional robots and wheeled vehicles, the robot deforms elastically to make ground contact over a relatively large ...
