I was just cracking with fatigue.

Corrosion fatigue-crack growth characteristics are important for the design of marine and off-shore structures.
Design of critical components requires data on fatigue-crack growth rate at very low frequencies of the order of 10?2 to 10?3 Hz.
The FAA has issued an Airworthiness Directive for the Bell 206L, 206L-1, 206L-3 and 206L-4 prompted by two accidents in which investigations revealed a main rotor blade failed because of fatigue cracking.
After removal of the clutch and pressure plate, a close inspection finds the metal fatigue cracks, which caused the clutch system's inability to release.
Federal investigators say the entire length of a 5-foot-long tear in the skin of a Southwest Airlines Boeing 737 shows evidence of pre-existing fatigue cracking.

In science:

In the case of strong fatigue — case 1. — the fractal dimensions for shear and isotropic tension are considerably lower than the fractal dimension of DLA, which is the result of the observed stability of the crack tips.

Dowling (1993, page 706) describes how increased cycle rate may affect the crack growth rate in per cycle fatigue testing.
A Review of Accelerated Test Models
Some fatigue tests are conducted to estimate crack growth rates, often as a function of explanatory variables like stress and temperature.

It is noteworthy that fatigue failure due to propagation of an initial crack was the main motivation for the Birnbaum–Saunders distribution.
