Want to answer this question...........
When soldier first got issued their kelvar, the quartermaster would tell each and everyone.
-Replace it once you got hit or bend it
When a bullet proof vest got hit more than once. It will destroy the layer structure of the fabric and crack or dent the ceremic plating.......
But the catch it, you cannot get hit more than once in you vest, not by one bullet....
You can suffer multiple hit and they will still catch it all (I tried, i took 3 hit from an AK and still survive)
But when you got hit the next time around. If you still wearing the same vest, you better pray they don't hit the same spot or general area...
