Design charts for seismic pressures against rigid walls subjected to horizontal earthquake shaking are presented for both uniform and nonuniform backfills. Solutions are based on a simplified model of soil response which gives results that agree almost exactly with rigorous solutions. Peak seismic thrusts are presented for three different soil profiles. For each profile, 250 combinations of gro...

We demonstrate that the free motion of any two-dimensional rigid body colliding elastically with two parallel, flat walls is equivalent to a billiard system. Using this equivalence, we analyze the integrable and chaotic properties of this new class of billiards. This provides a demonstration that coin tossing, the prototypical example of an independent random process, is a completely chaotic (B...

The magnetostatic interaction between two oppositely charged transverse domain walls (TDWs) in adjacent Permalloy nanowires is experimentally demonstrated. The dependence of the pinning strength on wire separation is investigated for distances between 13 and 125 nm. The results can be described fully by considering the distribution of magnetic charge within rigid, isolated TDWs. Alternative DW ...

in this paper, based on soil plasticity and pseudo-static methods, necessary equations have been derived for determination of total active thrusts due to layered backfill on rigid retaining walls using limit equilibrium approach. for this purpose, the reaction force applied on the failed wedge due to granular backfill has been determined using kotter’s equations. the total lateral thrust and th...

An analytical solution is derived for the acoustic streaming generated by two orthogonal standing waves in a fluid confined between two plane rigid walls. It is assumed that the standing waves have the same frequency but, in general, are out of phase. The main restriction is that the boundary layer thickness is much smaller than the acoustic wavelength. It is shown that the acoustic streaming g...

This paper presents the acoustic and structure characteristics of chambers with elastic/rigid baffles elastic walls using a novel formulation. The fluid is assumed to be compressible a...

In this paper, the sloshing response of liquid in a two dimensional rigid rectangular tank with rigid baffles is investigated using boundary element technique. A baffle is a supplementary structural element which supplies a kind of passive control on the effects of ground shaking. The complicated liquid domain is divided into two simple sub-domains so that the liquid velocity potential in each ...
