Editorial Reviews

From Publishers Weekly

Why can you bend a piece of taffy into all kinds of shapes while a peppermint stick breaks if you push on the middle of it? Why does adding carbon to iron make the resulting metal, steel, stronger, whereas adding sulfur brittles it, making it more liable to break? Eberhart, a professor at the Colorado School of Mines, explains the chemistry of metals and other materials to answer these and similar questions. Scientists still have much to learn about how planes of atoms slide over one another when a substance bends, or why impurities can toughen an alloy. In the past, scientists and manufacturers designed new products on a wing and a prayer, hoping that they wouldn't break. The Titanic went down in large part, Eberhart explains, because the iron used in the ship's hull had been made brittle by sulfur, allowing the iceberg to rip through it easily. Today metallurgists have to be able to develop materials with the exact properties needed to avoid another such disaster-think of the Challenger or of an airplane breaking up in flight because a tiny crack was exacerbated by increasing and decreasing air pressure. Hydrogen-powered cars are still in the future because hydrogen embrittles most substances it comes into contact with, so new and tougher engines need to be designed to withstand it. Though Eberhard uses many examples from everyday life to illustrate his points, his discussion gets more specialized as the book progresses, making it best for science buffs.

From Booklist

In materials science, nothing succeeds like failure, for it prompts discovery of what caused a disaster. In trying to understand why things break, scientists like Eberhart know that a fracture starts at the level of atomic bonds, but determining precisely what forces a bond to break remains a mystery. Shake-and-bake metallurgy and glass manufacturing has taken technology pretty far, furnishing us with jet turbines and Corningware galore, but, as Eberhart explains, making engines even more powerful and ceramics more fracture resistant runs into roadblocks at the quantum-mechanical scale. Atoms drift around, making material more brittle, and bonds stretch and bend in certain angles, all aspects of the fracture problem that Eberhart has investigated. He translates the technicalities of this field into accessible layperson's terms, aided by autobiographical excursions into his experiences with research funding, and with the public's generally deficient appreciation of technological risk: nothing is unbreakable, though we (or tort lawyers) demand that everything should be so. A very readable work for technology buffs, especially those who enjoyed Edward Tenner's Why Things Bite Back (1996). Gilbert Taylor

No diagrams, no figures, no graphs.
David M. Giltinan
It should be required reading for all engineering students graduating, and I encouraged students to read it when I was teaching statics and dynamics.
After reading the book, I felt as if I knew the Author and would enjoy having dinner with him.

Why Things Break is one scientist's account of how he came to came to investigate the science of fracture mechanics at a molecular level--not really the how, but the why. Although the narrative is sometimes rambling, and Dr. Eberhart digresses considerably at tangents to make his points, the stories are well worth reading. It is also illustrative of the career of a scientist tackling a field that is new: full of obstacles to be overcome.
Particularly interesting--at least I found them so--are the stories of creating ever tougher and harder materials, from metal to ceramics, starting with ancient techniques thousands of years ago. If you've ever wondered how the Samurai made their swords, or how steel ultimately replaced bronze in the case of weapons, Eberhart's vignettes will delight you. The case study of Corning's Corelle line is especially instructive in demonstrating the pitfalls of trying to make commercially viable materials that don't break easily, and often one gets the impression this was a solution looking for a problem. Other fascinating examples include the sinking of the Titanic, the armor aboard the USAF's C141, and litigation involving the fracturing of a cast-iron pump.
Most of the science presented will be understandable to an arts major, although on occasion the chemistry might prove hard going--sometimes explanations in science can be tough! On pages 142-143, the author makes some errors: the WWII aircraft he cites--the Supermarine Spitfire and the Mitsubishi Zero--were not mostly made of wood; rather new aluminum alloys were used. Perhaps Erhard was thinking of the twin-engine DeHavilland Mosquito fighter-bomber.
My only criticism is that the real why of things breaking is really relegated to a couple of chapters at the end of the book, but possibly this is because still so little is known about the subject.

I bought this book because it appeared to be aimed at showcasing the field of Fracture Mechanics to the lay person - certainly a daunting task in view of the depth of knowledge normally required to understand 'why things break". I wanted to see how the author would approach such a difficult subject (and without any pictures!). To my pleasant surprise this book was much more than an attempt to do "technology transfer". Eberhart has written a semi-autobiographical text that immerses the reader in the author's metamorphosis from a young child wondering about breaking atoms in butter with his knife to a full-fledged academic professor and researcher who asks and answers "why", not "how" or "when", but "why" something broke or failed. The examples given range from understanding how glass shatters, how Correlle ware is not really unbreakable, to the tragedy of the Challenger accident and the need to listen to engineers when they become wary about a material or system entering an unknown environment. Eberhart does lament the "pecking order" of science and the politically correct way that research funding in North America is meted out, but this, in my view, is an accurate reflection of how the approach our government agencies and industries are taking to funding fundamental research is leading our society towards mediocrity, inhibiting development of revolutionary ideas that can transform society into better ways to do things much quicker. While a conservative approach can provide a safer and lower risk result, it also can significantly slow the rate at which new ideas bubble to the surface. Research must be risk-taking by its very nature.Read more ›

I was attracted to this book after hearing the author on a radio interview and then reading the reviews on Amazon. I am not much of a science enthusiast, a little goes a long way, but I do like books about scientists. Both reader reviews seemed to indicate that "Why things break" is just that kind of book and it is. I so enjoyed following Dr. Eberhart's scientific development from a small child, concerned that cutting an atom would cause a nuclear explosion, to his eventual theories about bonds. Though some of this was over my head, I did feel as if I was participating in Dr. Eberhart's journey of discovery and learning a lot about materials on the way.
After reading the book, I felt as if I knew the Author and would enjoy having dinner with him.

This book is the author's personal story of how he uncovered a (conceptually) simple explanation for the fracturing and shearing of materials, and metals in particular. As Eberhart puts it:

"When these angles [characteristic of the charge density around atoms in a material] vanished, the bonds resisting shear would break. So it also seemed reasonable that the smaller this angle, the more closely the charge density of the native metal resembled that of the deforming substance...[similarly] the competition between ductile and brittle behavior would boil down to comparing different angles. A ductile material would be one in which the angle that changed during shear was small compared to the changing angle during elongation." [Page 236]

Eberhart tells his story of discovery through the experience of his life, beginning with experiments he conducted with toys when only 6 years old. Along the way he illustrates the importance of material design by dissecting the cause of failure in some notorious historical examples, such as:

1) Aloha flight 243

2) The Titanic

3) Space shuttle Challenger

Aloha flight 243 was doomed by metal fatigue and crack propagation. The Titanic was doomed by, among other things, a captain who was sailing too fast in iceberg-infested waters, and because the steel used in Titanic had too much sulfur, causing the steel to be brittle in the cold Atlantic. Challenger was doomed by managers who overrode the technical advice of engineers who advised against launch, and by rubber O-rings that hadn't enough plasticity at the cold temperatures present at launch.

Eberhart does a nice job of placing material properties in a very broad historical context.
