The importance of accurate time-integration in the numerical modelling of P-wave propagation [PDF]
, 2017 The numerical dissipation characteristics of the Newmark and generalised-α time-integration schemes are investigated for P-wave propagation in a fully saturated level-ground sand deposit, where higher frequencies than those for S-waves are of concern ...

Calculating the state parameter in crushable sands [PDF]
, 2019 The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]
, 2009 In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).

A Microscopic Definition of Liquefaction for Sand
Procedia Earth and Planetary Science, 2012 AbstractTraditional theoretical and experimental investigations of the mechanical behavior of granular media such as sand are restricted by the limited quantitative information about what actually happens internally. The discrete element method (DEM) was developed as a technique to examine the micromechanics of granular media for this purpose.
