What is Fracture Mechanics and
why do you care?
Fracture Mechanics is all about figuring out
how cracks think: where are they going to pop up next, are they going to grow
or just hang out where they are?
How often do you think about cracks? Never, right. Except when you're trying

see more about that later in this section.
