| Jan 9 at 21:35 | comment | added | kamran | @JohnBremer300, ductility is the capacity of a metal or a structure to deform under applied stress and absorb much energy before cracking or in a structure before collapsing. A metal could have very high yield but not be ductile, so it will have almost a sharp point in the stress vs strain curve past which it will break. But a very ductile rod can be pulled to a thin, long wire without breaking. The paradigm of push-over seismic design counts on the ductility of yielded members not to fail even after large plastic deformations at plastic hinges. | |
