On the micromechanics of crushable aggregates

McDowell, G. R., Bolton, M. D.·1998·Géotechnique

Abstract

This paper presents a study of the micromechanical behaviour of crushable soils. For a single grain loaded diametrically between flat platens, data are presented for the tensile strengths of particles of different size and mineralogy. These data are shown to be consistent with Weibull statistics of brittle fracture. Triaxial tests on different soils of equal relative density show that the dilatational component of internal angle of friction reduces logarithmically with mean effective stress normalized by grain tensile strength. The tensile strength of grains is also shown to govern normal compression. For a sample of uniform grains under uniaxial compression, the yield stress is related to the average grain tensile strength. If particles fracture such that the smallest particles are in geometrically self-similar configurations under increasing geotoscopic stress, with a constant probability of fracture, a fractal geometry evolves with the successive fracture of the smallest grains, in agreement with the available data. A new work equation predicts that the evolution of a fractal geometry gives rise to a linear compression line when voids ratio is plotted against the logarithm of geotoscopic stress, in agreement with published data. Cet exposé présente une étude du comportement micro mécanique des sols concassables. Pour un seul grain chargé de manière diamétrale entre des platines plates, nous présentons les données de résistance à la rupture des particules de différentes dimensions et minéralogies. Nous montrons que ces données correspondent aux statistiques de Weibull sur la rupture de fragilité. Les essais triaxiaux sur divers sols de meême densité relative montrent que le composant de dilatation de ľangle interne de friction baisse de manière logarithmique en mê"me temps que la contrainte effective moyenne normalisée par la r6sistance à la rupture du grain. Nous montrons aussi que la résistance à la rupture des grains gouverne la compression normale. Pour un échantillon de grains uniformes sous compression uniaxiale, la limite 61astique est liée à la rupture moyenne des grains. Si la rupture des particules est telle que les plus petites particules sont dans des configurations à similitude géomé trique intrinsèque sous un effort geotoscopique de plus en plus grand, avec probabilité constante de rupture, une géométrie fractale apparaît avec la rupture successive des grains les plus fins, en accord avec les données disponibles. Une nouvelle équation de travail prédit que ľévolution de la géometrie fractale provoqueľPapparition ďune ligne de compression linéaire quand le taux de pores est représenté sous forme de courbe par rapport au logarithme de ľeffort geotoscopique, en accord avec les données pub-liées.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
