In April 1985 two workshop meetings were arranged in two consecutive weeks: the Second CSNI Informal Workshop on Ductile Fracture Test Methods was organised and hosted by OECD, Paris, and chaired by F.J. Loss. It took place on 17th-19th April 1985. It dealt primarily with experimen- tal techniques in elastic-plastic fracture mechanics and standardisation of J and JR-curve tests. In order to enable overseas participants to Ic attend this meeting and the Workshop on the CTOD Methodology the latter was scheduled for 23th-25th April 1985 at the GKSS-Forschungs- zentrum Geesthacht. Thus, a number of participants took part in the debates on the merits of the CTOD concept, having the state-of-the-art of the J-integral philosophy freshly in mind. In this respect, the twin arrangement was very fruitful. Three days were planned for the meeting, in order to have sufficient time for presenting and discussing 27 contributions. Because of the workshop-type of the meeting several contri butions on on- going research were presented which were not intended to be published. The Studiengesellschaft zur F5rderung der Kernenergieverwertung in Schiff- bau und Schiffahrt e.V.(KEST) and the Stiftung Volkswagenwerk generously sponsored the workshop, which is gratefully acknowledged. Thanks are due to GKSS-Forschungszentrum Geesthacht for hosting the meeting.

This book presents a broad survey of models for critical and catastrophic phenomena in the geosciences, with strong emphasis on earthquakes. It assumes the perspective of statistical physics, which provides the theoretical frame for dealing with complex systems in general. This volume addresses graduate students wishing to specialize in the field and researchers working or interested in the field having a background in the physics, geosciences or applied mathematics.

Vibro compaction and vibro stone columns are the two dynamic methods of soil improvement most commonly used worldwide. These methods have been developed over almost eighty years and are now of unrivalled importance as modern foundation measures. Vibro compaction works on granular soils by densification, and vibro stone columns are used to displace and reinforce fine-grained and cohesive soils by introducing inert material.This practical guide for professional geotechnical engineers and graduate students systematically covers the theoretical basis and design principles behind the methods, the equipment used during their execution, and state of the art procedures for quality assurance and data acquisition.All the chapters are updated in line with recent developments and improvements in the methods and equipment. Fresh case studies from around the world illustrate the wide range of possible applications. The book concludes with variations to methods, evaluates the economic and environmental benefits of the methods, and gives contractual guidance.The Open Access version of this book, available at http://www.taylorfrancis.com, has been made available under a Creative Commons Attribution-Non Commercial-No Derivatives 4.0 license

This is the story of the friendships that defined one of America's most beloved Presidents. Chris Matthews, who has been following and studying the Kennedys most of his life, has interviewed President Kennedy's closest confidants - family, friends, and those who served with him--to create a moving portrait of a man many loved but few really understood. These friends were with Jack Kennedy as he took surprising risks, struggled with chronic illness, and repeatedly confronted "the thin membrane between life and death." As Matthews describes it, Jack Kennedy was a rebel, an adventurer, and a great enjoyer of life precisely because he understood its fragility. Being with Jack Kennedy was great fun for his friends. Now readers will share in that experience.

Vibro compaction and vibro stone columns are the two dynamic methods of soil improvement most commonly used worldwide. These methods have been developed over almost eighty years and are now of unrivalled importance as modern foundation measures. Vibro compaction works on granular soils by densification, and vibro stone columns are used to displace and reinforce fine-grained and cohesive soils by introducing inert material.This second edition includes also a chapter on vibro concrete columns constructed with almost identical depth vibrators. These small diameter concrete piles are increasingly used as ground improvement methods for moderately loaded large spread foundations, although the original soil characteristics are only marginally improved.This practical guide for professional geotechnical engineers and graduate students systematically covers the theoretical basis and design principles behind the methods, the equipment used during their execution, and state of the art procedures for quality assurance and data acquisition.All the chapters are updated in line with recent developments and improvements in the methods and equipment.

Written by three leading experts in the field, this textbook describes and explains all aspects of the scanning probe microscopy. Emphasis is placed on the experimental design and procedures required to optimize the performance of the various methods. Scanning Probe Microscopy covers not only the physical principles behind scanning probe microscopy but also questions of instrumental designs, basic features of the different imaging modes, and recurring artifacts. The intention is to provide a general textbook for all types of classes that address scanning probe microscopy. Third year undergraduates and beyond should be able to use it for self-study or as textbook to accompany a course on probe microscopy. Furthermore, it will be valuable as reference book in any scanning probe microscopy laboratory. Novel applications and the latest important results are also presented, and the book closes with a look at the future prospects of scanning probe microscopy, also discussing related techniques in nanoscience. Ideally suited as an introduction for graduate students, the book will also serve as a valuable reference for practising researchers developing and using scanning probe techniques.

Wind power plants teaches the physical foundations of usage of Wind Power. It includes the areas like Construction of Wind Power Plants, Design, Development of Production Series, Control, and discusses the dynamic forces acting on the systems as well as the power conversion and its connection to the distribution system. The book is written for graduate students, practitioners and inquisitive readers of any kind. It is based on lectures held at several universities. Its German version it already is the standard text book for courses on Wind Energy Engineering but serves also as reference for practising engineers.

This brief provides guidance for the application of cohesive models to determine damage and fracture in materials and structural components. This can be done for configurations with or without a pre-existing crack. Although the brief addresses structural behaviour, the methods described herein may also be applied to any deformation induced material damage and failure, e.g. those occurring during manufacturing processes. The methods described are applicable to the behaviour of ductile metallic materials and structural components made thereof. Hints are also given for applying the cohesive model to other materials.
