The first published study appeared in 1837 on mining conveyor chains that failed in service. By the end of the 20th century, over 100,000 papers had been written on the subject, and the problem is still not solved. The reason is that fatigue failure depends on a wide range of interacting factors: residual stress, thermal processing, surface condition, environment, and most fundamentally, the microstructure of the material itself. The Aloha Airlines Flight 243 accident, where fatigue cracks in fuselage lap joints caused a section of the cabin roof to separate in flight, is one example among many that drove enormous investment in understanding how cracks initiate and grow under cyclic loading.</p>
