To prevent accidents, we must first find out what causes them. Physical properties of the materials use in aircraft construction are often involved in these accidents. Stress, strain, fracture, and fatigue are all part of the material factors that have to be unravelled. This book is designed to help investigators and others interested in determining the causes of aircraft accidents in which material failure is involved; it is suited for the engineering technician or professional engineer who may be involved in accident investigation for the first time. |
