This book presents guidelines on quantitative and qualitative measures of the geometric features and imperfections of welds to ensure that it meets the fatigue strength requirements laid out in the recommendations of the IIW (International Institute of Welding). Welds that satisfy these quality criteria can be assessed in accordance with existing IIW recommendations based on nominal stress, structural stress, notch stress or linear fracture mechanics. Further, the book defines more restrictive acceptance criteria based on weld geometry features and imperfections with increased fatigue strength. Fatigue strength for these welds is defined as S-N curves expressed in terms of nominal applied stress or hot spot stress. Where appropriate, reference is made to existing quality systems for welds.In addition to the acceptance criteria and fatigue assessment curves, the book also provides guidance on their inspection and quality control. The successful implementation of these methods depends on adequate training for operators and inspectors alike. As such, the publication of the present IIW Recommendations is intended to encourage the production of appropriate training aids and guidelines for educating, training and certifying operators and inspectors.

Avoiding or controlling fatigue damage is a major issue in the design and inspection of welded structures subjected to dynamic loading. Life predictions are usually used for safe life analysis, i.e. for verifying that it is very unlikely that fatigue damage will occur during the target service life of a structure. Damage tolerance analysis is used for predicting the behavior of a fatigue crack and for planning of in-service scheduled inspections. It should be a high probability that any cracks appearing are detected and repaired before they become critical. In both safe life analysis and the damage tolerance analysis there may be large uncertainties involved that have to be treated in a logical and consistent manner by stochastic modeling.
This book focuses on fatigue life predictions and damage tolerance analysis of welded joints and is divided into three parts. The first part outlines the common practice used for safe life and damage tolerance analysis with reference to rules and regulations. The second part emphasises stochastic modeling and decision-making under uncertainty, while the final part is devoted to recent advances within fatigue research on welded joints. Industrial examples that are included are mainly dealing with offshore steel structures. Spreadsheets which accompany the book give the reader the possibility for hands-on experience of fatigue life predictions, crack growth analysis and inspection planning. As such, these different areas will be of use to engineers and researchers.

Most books on soldering work like cookbooks; they purport to offer the correct recipe for every task and each new situation. More realistically, this book helps engineers and quality controllers to adapt techniques and processes to changing situations along the electronics production cycle by affording them with an environment in which production problems can be solved through flexible thinking based on scientific fact. It achieves this aim in great part by providing a clear and coherent blending of the chemical and physical theory behind soldering technology with practical applications in the electronics manufacturing industry. Throughout The Basics of Soldering the focus is on the complex interrelationships of the different parameters. Through-hole and surface-mounted joining are treated in full, as are cleaning and statistical quality control. Instead of just the usual "cooking recipes" found in most books on the subject, readers will find well-founded scientific theories combined with exhaustive coverage of contemporary methods and materials and a thorough understanding of real-world applications of soldering technology. The result is faster problem solving, more effective training of new personnel, and a better understanding of soldering and related technologies. Because it is based on a successful seminar series, The Basics of Soldering is also an excellent teaching tool, well suited to both graduate and upper level undergraduate courses.

Human development is a long and steady process that began with stone tool making. Because of this skill, humans were able to adapt to climate changes, discover new territories, and invent new technologies. "Pressure knapping" is the common term for one method of creating stone tools, where a larger device or blade specifically made for this purpose is use to press out the stone tool. Pressure knapping was invented in different locations and at different points in time, representing the adoption of the Neolithic way of life in the Old world.

Recent research on pressure knapping has led for the first time to a global thesis on this technique. The contributors to this seminal work combine research findings on pressure knapping from different cultures around the globe to develope a cohesive theory.
