Say what!?

Metal can be made stronger by bending it then straightening it again? That's
patently absurd. But, you miss the point, bend a bumper and leave it be and
it will never hit anything again. (That's a joke son, and is the point yo
missed.)

You might think it's absurd but it happens to be correct. Some metals
are specifically designed to start off soft and increase in strength
through use. The correct term IS called work hardening and it does work.

The steel DOES become stronger but as it does, it's brittleness
increases as well, which is why as you keep bending it it gets harder to
bend but eventually cracks and breaks.

Some alloys can work harden so much (especailly some aluminum ones)
that when you bend it as soon as the bending motion stops it becomes
so "hard" that any further attempt to bend it more will break it.

Can you give an automotive application that actually fits the discussion?

Any metal on my Jeep that has been bent is weaker and bends easier if it is
straightened. This is particularly notable on the fenders and bumpers, which
is the topic.
