Not necessarily. Think of a car. If you do 0-60 in 5 secs and 60-0 in 5 nothing happens. But drive it into a load of soft air bags that do the same deceleration and you will see compression on the front.

In addition stretch isn’t the same as compression and certain shapes are better one way than another. Think like a submarine. Very good at withstanding huge pressure from outside, from inside not so much.
