Rockfall Engineering is an up-to-date, international picture of the state of the art in rockfall engineering. The three basic stages of rockfalls are considered: the triggering stage, the motion stage, and the interaction with a structure stage; along with contributions including structural characterization of cliffs, remote monitoring, stability analysis, boulder propagation, design of protection structures an risk assessment. Academic contributions are illustrated by practical examples, and completed by engineering contributions where practical purposes are thoroughly considered. This title is intended for engineers, students as well as researchers.[Source inconnue]
Advances in multi-physics and multi-scale couplings in geo-environmental mechanics by François Nicot( )

10 editions published between 2017 and 2018 in English and held by 216 WorldCat member libraries worldwide

Advances in Multi-Physics and Multi-Scale Couplings in Geo-Environmental Mechanics reunites some of the most recent work from the French research group MeGe GDR (National Research Group on Multiscale and Multiphysics Couplings in Geo-Environmental Mechanics) on the theme of multi-scale and multi-physics modeling of geomaterials, with a special focus on micromechanical aspects. Its offers readers a glimpse into the current state of scientific knowledge in the field, together with the most up-to-date tools and methods of analysis available. Each chapter represents a study with a different viewpoint, alternating between phenomenological/micro-mechanically enriched and purely micromechanical approaches. Throughout the book, contributing authors will highlight advances in geomaterials modeling, while also pointing out practical implications for engineers. Topics discussed include multi-scale modeling of cohesive-less geomaterials, including multi-physical processes, but also the effects of particle breakage, large deformations on the response of the material at the specimen scale and concrete materials, together with clays as cohesive geomaterials. The book concludes by looking at some engineering problems involving larger scales
Failure in Geomaterials : a Contemporary Treatise by Richard Wan( )

9 editions published between 2016 and 2017 in English and Undetermined and held by 210 WorldCat member libraries worldwide

Failure in Geomaterials offers a unified view of material failure as an instability of deformation modes framed within the theory of bifurcation. Using mathematical rigor, logic, physical reasoning and basic principles of mechanics, the authors develop the fundamentals of failure in geomaterials based on the second-order work criterion. Various forms of rupture modes and material instabilities in granular materials are explored both analytically and numerically with lab experimental observations on sand as a backdrop. The authors provide a clear picture of inelastic deformations and failure of geomaterials under various loading conditions. A unique feature of the book is the systematic application of the developed theory to the failure analysis of some selected engineering problems such as soil nailing, landslides, energy resource extraction, and internal erosion in soils
Stability of discrete non-conservative systems by Jean Lerbet( )

4 editions published between 2020 and 2021 in English and Undetermined and held by 180 WorldCat member libraries worldwide

Stability of Discrete Non-conservative Systems first exposes the general concepts and results concerning stability issues. It then presents an approach of stability that is different from Lyapunov which leads to the second order work criterion. Thanks to the new concept of Kinematic Structural Stability, a complete equivalence between two approaches of stability is obtained for a divergent type of stability. Extensions to flutter instability, to continuous systems, and to the dual questions concerning the measure of non-conservativeness provides a full, fresh look at these fundamental questions. A special chapter is devoted to applications for granular systems

Modélisation par éléments discrets de l'impact des laves torrentielles granulaires sur des structures rigides et flexibles by Adel Albaba( )

1 edition published in 2015 in English and held by 2 WorldCat member libraries worldwide

Les risques naturels tels que les laves torrentielles constituent des menaces réelles pourles zones urbanisées de montagne. Les bâtiments et infrastructures peuvent être exposésà de grandes forces d'impact en cas d'évènement extrême. La réduction de cette menace,par des ouvrages de protection, impose de quantifier l'impact de ces écoulements sur lesstructures, qu'elles soient flexibles ou rigides.Tout d'abord, un écoulement granulaire sec, composé de particules non-sphériquesglissant sur un plan incliné, est modélisé en utilisant une loi de contact visco-élastiqueavec critère de rupture de Mohr-Coulomb. Des données expérimentales de la littératureont été utilisé pour calibrer et valider le modèle. À cette fin, la forme de la particule,l'épaisseur de l'écoulement et la forme finale du dépôt sur le mur sont considerés. Lavalidation est basée sur l'impact sur un mur rigide divisé en six segments. La principalecontribution de la force totale normale appliquée sur le mur est due à la composantedynamiques. La distribution hétérogène de la force normale sur chaque partie du murest due au développement des chaînes de force différent pour chaque arrangement desparticules.Ensuite, un filet est modélisé en utilisant des éléments cylindriques. L'impact sur lefilet est modélisé en utilisant le même modèle d'écoulement que précédemment. Le rôledes dissipateurs d'énergie apparaît essentiel pour réduire la force d'impact sur le filet etlimiter la force appliquée sur les points d'ancrage latéraux.Pour la première fois, des simulations montrent que pour un même écoulementgranulaire la force d'impact est plus élevée pour un obstacle rigide, avec une différencede 50% par rapport à un obstacle flexible. les simulations permettent de définir quelquesrecommandation pour le dimensionnement des filets. Il est constaté que l'utilisationviiid'un maillage de filet plus petit que D90 de l'écoulement est acceptable en termes decapacité à retenir les matériaux en écoulement. En plus, si le câble en bas du filet n'estpas fixé, le filet pourrait perdre totalement sa capacité de retenue

Modélisation de l'impact d'un bloc rocheux sur un terrain naturel : application à la trajectographie des chutes de blocs by Franck Bourrier( Book )

2 editions published in 2008 in French and held by 2 WorldCat member libraries worldwide

This thesis is dedicated to the study of falling rocks bouncing on natural soils in order to improve the models used for rockfall hazard assessment. The impact of a rock on a scree slope is modelled using the Discrete Element Method. The comparison between numerical results and half-scale experimental results of impacts on a coarse soil shows that the numerical model allows accurately predicting the bouncing of the rock for a reduced number of model parameters to be calibrated. The numerical results also emphasize that the interaction between the impacting particle and the granular soil is composed of three stages : the partial energy exchange from the impacting particle to the soil, the propagation of a shockwave from the impact point and the wave reflection on the substratum. The study of energy exchanges during these three stages allows defining the impacting particle bouncing occurrence diagram as well as three impact regimes. The statistical analysis of numerical results using Bayesian inference leads to the definition of a stochastic impact model. This model is relevant for rock velocity after impact depending on both rock velocity before impact and soil particles layout near the impact point. Finally, the stochastic impact model is integrated into trajectory analysis models which allows defining a global probabilistic approach of rockfall hazard assessment including protective structures design
Approche numérique couplée discret-continu appliquée aux ouvrages cellulaires impactés by Antonin Breugnot( )

1 edition published in 2011 in French and held by 2 WorldCat member libraries worldwide

Le cadre général de ce travail concerne la modélisation du comportement mécanique sous impact de merlons de protection contre les chutes de blocs rocheux. Les ouvrages ciblés sont à technologie cellulaire, et sont composés de gabions à enveloppe grillagée remplis de matériaux granulaires (pierres concassées ou mélange de sable et de déchiquetas de pneus). L'absence de recommandations relatives au dimensionnement de ce type de structure de protection a conduit à la mise en place du projet ANR REMPARe couplant expérimentations in situ et modélisations numériques. Dans le cadre de ce projet, une méthode numérique innovante couplant les approches discrète et continue a été développée. Localement, la méthode des éléments discrets est employée pour conserver la précision de modélisation dans les zones fortement sollicitées proches de l'impact. Le remblai technique aval, peu sollicité, a été discrétisé par une méthode continue aux différences finies. La jonction entre ces deux zones fait l'objet d'un couplage basé sur des critères de conservation d'énergie et de condition cinématique en déplacement. Un modèle de comportement pour les gabions a été proposé et calibré à partir d'essais expérimentaux réalisés à l'échelle de la cellule. Des simulations d'impacts sur un merlon de protection prototype ont été menées puis validées par comparaison avec les mesures issues des expérimentations en vraie grandeur. Afin d'améliorer la compréhension des mécanismes engendrés, l'étude paramétrique portant sur les propriétés des matériaux et les caractéristiques d'impact a permis d'évaluer leur influence sur le mécanisme d'impact
