What is ‘fatigue’? … and no I don’t mean feeling ‘tired’.
podcast episode with speaker Chris Jackson
Many reliability engineers know what fatigue is (in addition to feeling tired). Fatigue is an example of a ‘failure mechanism.’ A failure mechanism is the physical, chemical or electrical process that results in failure. Fatigue is interesting in that it allows something to fail without it ever being exposed to stresses that are beyond its strength. How does this happen? Fatigue is based on cracks. Cracks magnify stresses at their tips. So cycling stresses can have the effect of incrementally (and sometimes very slowly) increasing the crack length at the tip. Fatigue has caused all manners of failures that have surprised us throughout the history of engineering. But now we have learned so much more about this really fascinating failure mechanism can cause steel, aluminium and other material to fail, even when the stresses they experience are tiny. Want to learn more about fatigue? And how you can help prevent it? Join us for this webinar.
