Re: Twisting of rebar

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I can see how a long enough rebar can be twisted 360 degrees.  The thing is - will is stay that way, or can the needed plastic (permanent) torsional deformation to 90 degrees be achieved without rendering the rebar non-usable?
By the way, coming from so many grateful engineers, those beers may be really bad for your health.  Hopefully, as it goes now, the government will force you to stay healthy...
