The festive mood of a children's birthday party was suddenly halted by the sound of shattering glass; a pitcher of lemonade had broken on the floor. For an instant, tension filled the room as each child looked to see which of them would receive the blame for the accident. In a few seconds relief spread through the group as they realized that the father, not a child, was the cause of the calamity. "It's OK," said one of the small girls. "My daddy is allowed to break things; that's his job."
Her father is indeed one of a growing group of research engineers who studies how and why things break, and how to prevent breakage. Their attention is directed primarily toward structural materials, not dinnerware, and they are called fracture mechanics engineers.
Consequences of Fracture...

...acture mechanics enters its fourth decade, it offers the promise of greater safety and reliability in our engineering structures. This can benefit our lives in many ways - primarily through the saving of billions of dollars and the reduced threat of fracture-related accidents. Continued emphasis on both research and education in this field is as an essential part of our future well being. vbcrlf
