Rock Mechanics Achievements And Ambitions

Rock Mechanics: Achievements and Ambitions contains the papers accepted for the 2nd ISRM International Young Scholars’ Symposium on Rock Mechanics, which was sponsored by the ISRM and held on 14–16 October 2011 in Beijing, China, immediately preceding the 12th ISRM Congress on Rock Mechanics. Highlighting the work of young teachers, researchers and practitioners, the present work provides an important stimulus for the next generation of rock engineers, because in the future there will be more emphasis on the use of the Earth’s resources and their sustainability, and more accountability of engineers’ decisions. In this context, it is entirely appropriate that the Symposium venue for the young scholars was in China — because of the rock mechanics related work that is anticipated in the future. For example, in the Chinese Academy of Sciences report, “Energy Science and Technology in China: A Roadmap to 2050”, it is predicted that China’s total energy demand will reach 31, 45, 61 and 66 x 108 tce (tonnes of coal equivalent) in 2010, 2020, 2035, 2050. The associated per capita energy consumption for the same years is estimated at 2.3, 3.1, 4.1 and 4.6 tce. This increasing demand will be met, inter alia, by the continued operation and development of new coal mines, hydroelectric plants and nuclear power stations with one or more underground nuclear waste repositories, all of which will be improved by more modern methods of rock engineering design developed by young scholars. In particular, enhanced methods of site investigation, rock characterisation, rock failure understanding, computer modelling, and rock excavation and support are needed. The topics in the book include contributions on: - Field investigation and observation - Rock constitutive relations and property testing - Numerical and physical modeling for rock engineering - Information technology, artificial intelligence and other advanced techniques - Underground and surface excavation and reinforcement techniques - Dynamic rock mechanics and blasting - Predication and prevention of geo-environmental hazard - Case studies of typical rock engineering Many of the 200 papers address these topics and demonstrate the skills of the young scholars, indicating that we can be confident in the continuing development of rock mechanics and rock engineering, leading to more efficient, safer and economical structures built on and in rock masses. Rock Mechanics: Achievements and Ambitions will appeal to professionals, engineers and academics in rock mechanics, rock engineering, tunnelling, mining, earthquake engineering, rock dynamics and geotechnical engineering.

This book provides a new, necessary and valuable approach to the consideration of risk in underground engineering projects constructed within rock masses. There are Chapters on uncertainty and risk, rock engineering systems, rock fractures and rock stress, the design of a repository for radioactive waste, plus two major case examples relating to th

This unique compendium contains a vast systematized data of 14,000 experiments on high-velocity penetration into metals, concrete, reinforced concrete, and geological media which were published in the open literature (journal papers, reports, conference proceedings) during the last 70 years. Data presented in this edition are related to the initial and final stages of penetration and include: parameters which characterize mechanical and geometric properties of the striker and the shield; striking and residual velocities of projectile or depth of penetration; changes of mass and size of projectile; angles that determine the initial and residual position of the projectile; ballistic limit velocity; basic characteristics of plug and deformation of the shield.Unified form of data representation and common notations are used throughout the book. All information is presented in numerical form in SI units. The book also contains indices which allow a fast search of the authors' publications and related experiments. Theoreticians, design engineers and experimentalists will find this handbook a valuable reference material.

This two-volume, 1100 pages, 38 chapters book is a significantly expanded, revised and updated version of the monograph by the authors published in 2013 (Ben-Dor, G, Dubinsky, A, Elperin, T, 'High Speed Penetration Dynamics: Engineering Models and Methods,' Singapore: World Scientific Publishing Company). The contents increased by 60%, the number of titles in bibliography doubled and reached 1600; and the scope covers a range of new topics related to hypervelocity penetration, along with high-speed impact.Presented material is structured into two parts. The first part includes description and analysis of practically all known engineering models for calculating high-speed penetration of projectiles into concrete, metals, geological shields, adobe, and gelatine.The second part focuses on the use of approximate models for solving conventional and non-standard problems of penetration mechanics including prediction and optimization of protective properties of monolithic and multi-layered shields against high-speed projectiles and space debris; shape optimization of high-speed projectiles penetrating into various media; modelling of penetration and optimal control of penetrators equipped with jet thrusters; and investigation of the efficiency and optimization of segmented projectiles. The book includes comprehensive overviews on basic classes of problems in high-speed penetration mechanics.This is a indispensable reference guide for scientists, engineers, and students specializing in the field of high-speed and hypervelocity penetration mechanics.
