Horizontal Vibrations of Embedded Foundation in Multi-Layered Poroelastic Soils

open access: yesJournal of the Civil Engineering Forum, 2019
In this paper, the dynamic response of rigid foundations of arbitrary shape embedded in multi-layered poroelastic soils subjected to time-harmonic horizontal loading is presented.

Physical significance of the curvature varifold-based description of crack nucleation

open access: yes, 2010
The nucleation and/or growth of cracks in elastic-brittle solids has been recently described in [14] in terms of a special class of measures and with a variational technique requiring the minimization of a certain energy over classes of bodies. Here, the

On preconditioning strategies for geotechnics [PDF]

open access: yes, 2005
Iterative solvers are of increasing interest in geomechanics with the move towards 3D finite element modelling. Potentially, these methods can lead to reduced computational complexity as, unlike direct methods, they do not require the full system matrix ...

Quantum Structure in Economics: The Ellsberg Paradox

open access: yes, 2012
The 'expected utility hypothesis' and 'Savage's Sure-Thing Principle' are violated in real life decisions, as shown by the 'Allais' and 'Ellsberg paradoxes'. The popular explanation in terms of 'ambiguity aversion' is not completely accepted.

Instability analysis procedure for 3-level multi-bearing rotor-foundation systems [PDF]

open access: yes
A procedure for the instability analysis of a three-level multispan rotor systems is described. This procedure is based on a distributed mass elastic representation of the rotor system in several eight-coefficient bearings. Each bearing is supported from
