In the paper the equations of vibratory motion for circular sandwich plates are derived. The plate under consideration is supposed to possess a soft core with special polar orthotropy. Free axisymmetric vibration modes of a circular plate clamped all around the outside radius are numerically analyzed...
As train speeds increase, the aerodynamic effects generated during the passage of high-speed trains in tunnels become more pronounced. This article investigates the influence of line spacing on the aerodynamic forces during the passage of high-speed trai
These age-associated changes in motor performance are explained, in part, by altered muscle activity from three hand muscles and out-of-plane forces. Quantifying the ability to produce steady fingertip forces against low-friction surfaces may be a better indicator of impairment and disability than ...
The force component directly proportional to the linear acceleration is smaller by a factor proportional to the ratio of wing thickness and stroke amplitude; its net contribution is zero in hovering. The ratio of wing inertia and fluid force is proportional to the product of the ratio of wing ...
Effects of London‐van der Waals forces on the thinning of a dimpled liquid film as a small drop or bubble approaches a horizontal solid plane When a small drop or bubble approaches a solid surface, a thin liquid film forms between them, drains, until an instability forms and coalescence ...
process involves the replication of the mould surface onto the surface of the part. Moreover, depending on the material being processed and the geometry of the part, it can be difficult to demould the part because the moulding tends to shrink around the mould surface, when a core is needed...
Measurements are presented of the forces experienced on a series of two-dimensional bodies in plane oscillatory flow over the Keulegan-Carpenter number range 3 to 70. As KSUPc increases above a value of about 15, flat plates, diamond and... PW Bearman,JMR Graham,S Singh - Pitman Advanced ...
In this paper, a mixed mode Dugdale–Barenblatt model has been established for a semi-infinite crack in an ideally elastic-plastic thin plate loaded by a pair of self-equilibrating concentrated forces at the crack lips. Cohesive forces are introduced into a plastic strip in the elastic body....
In this paper, three-dimension exciting bearing forces of one blade and the whole propeller under nonuniform ship's wake were predicted, and the influence of cross flows on these exciting forces was studied. All simulations were carried out using a commercial solver, STAR-CCM+. To obtain the...
The influence of the third order elastic constants to the generalized Rayleigh wave dispersion in a pre-stressed stratified half-plane Within the framework of the piecewise homogeneous body model with the use of the three-dimensional linearized theory of elasticity the influence of the thi... SD ...
