The content of this book is divided into nine chapters. This short chapter is an introduction to the following chapters that discuss vari­ous subjects related to “Computational Welding Mechanics”. “Com­puter Simulation of Welding Processes” is the title of chapter two. The third chapter, “Thermal Analysis of Welds” provides the neces­sary background information for thermal stress […]

From the industry point of view, the most critical mechanical ef­fects of welding are cracking, distortion and buckling. The influence of welds on crack propagation in stress corrosion cracking, fatigue and fracture is also a concern. The difficulties of obtaining relevant material properties, in mak­ing experimental measurements to validate predictions and the com­plexity of the […]

Historically, arc welding began shortly after electrical power be­came available in the late 1800s. Serious scientific studies date from at least the 1930s. The failure of welded bridges in Europe in the 1930s and the American Liberty ships in World War II did much to stimulate research in welding in the 1940s. In the USA, […]

Welding as a fabrication technique presents a number of difficult problems to the design and manufacturing community. Nowhere is this more evident than in the aerospace industry with its emphasis on performance and reliability and yet where materials are seldom se­lected for their weldability. Developments in calculating the thermal cycle and elastoplastic stress-strain cycle have […]
