Book excerpt: Wood is a naturally growing material used from ages, but the applications for a single wood piece are limited by the shape and girth of the tree from where the piece is derived. Assembling wood pieces together enables working around this issue. Development in the last 10 years have highlighted the possibility to weld wood instead of the more classical mechanical fastener or polymeric adhesive already known as bonding techniques. While offering high processing speed and ecological advantages, past research have reported poor water resistance of the welded joint. Furthermore, high scatter of the mechanical properties and a lack of quantitative dependence with moisture content prevent performing accurate prediction regarding the joint failure. The aim of this work is to investigate the fracture behavior of the welded joint in a range of moisture content below the fibre saturation point. Combined experimental and numerical work are use to characterize the effects of moisture content and mixed mode loadings and a finite element model is suggested to predict crack propagation in the welded joint.

Download or read book Wood Fracture Characterization written by Marcelo F. S. F. de Moura. This book was released on 2018-06-14. Available in PDF, EPUB and Kindle. Book excerpt: Wood Fracture Characterization provides a guide to the application of modern fracture mechanics concepts to wood materials used in structural engineering, which commonly involve discontinuities and irregularities. The authors cover the tests, data reduction schemes and numerical methods devised for wood structural applications, based on cohesive zone analysis, and used to validate experimental-based methodologies. Five detailed Case Studies are included to link theory with engineering practice. This important new text explains the basics of fracture mechanics, and extends them as needed to cover the special behaviour of an anisotropic wood materials.

Book Synopsis Fracture and Fatigue of Welded Joints and Structures by : K Macdonald

Download or read book Fracture and Fatigue of Welded Joints and Structures written by K Macdonald. This book was released on 2011-04-19. Available in PDF, EPUB and Kindle. Book excerpt: The failure of any welded joint is at best inconvenient and at worst can lead to catastrophic accidents. Fracture and fatigue of welded joints and structures analyses the processes and causes of fracture and fatigue, focusing on how the failure of welded joints and structures can be predicted and minimised in the design process.Part one concentrates on analysing fracture of welded joints and structures, with chapters on constraint-based fracture mechanics for predicting joint failure, fracture assessment methods and the use of fracture mechanics in the fatigue analysis of welded joints. In part two, the emphasis shifts to fatigue, and chapters focus on a variety of aspects of fatigue analysis including assessment of local stresses in welded joints, fatigue design rules for welded structures, k-nodes for offshore structures and modelling residual stresses in predicting the service life of structures.With its distinguished editor and international team of contributors, Fracture and fatigue of welded joints and structures is an essential reference for mechanical, structural and welding engineers, as well as those in the academic sector with a research interest in the field. - Analyses the processes and causes of fracture and fatigue, focusing predicting and minimising the failure of welded joints in the design process - Assesses the fracture of welded joints and structure featuring constraint-based fracture mechanics for predicting joint failure - Explores specific considerations in fatigue analysis including the assessment of local stresses in welded joints and fatigue design rules for welded structures
