Opis

Joints in components or structures incur a weight penalty, are a source of failure, cause manufacturing problems, and are unfortunately unavoidable in most structures ranging from aircraft, and spacecraft to ships and offshore platforms, to automobiles, bridges and buildings. An important requirement for the complete design of practical structures is the development of attachment methods and joint designs. Recent Advances in Structural Joints and Repairs for Composite Materials provides an up-to-date account of adhesively bonded and mechanically fastened joints and repairs. Audience: This book will prove to be an informative resource for all engineers and researchers involved with joining and repair of composite structures.
