According to recent research published in the Journal of Engineering Mechanics - Asce, "Stress transfer from concrete into steel is one of the fundamental mechanisms behind the significant ductility of reinforced concrete."
"Considering the low value of cracking strain of plain concrete, it is the stress transfer that takes place during debonding when the steel strain approaches the yield limit at a level which is an order of magnitude larger than the cracking limit of concrete. This technical note examines the difference of ''tension softening'' of plain concrete versus ''tension stiffening'' of reinforced concrete which describes the stress transfer mechanism ...
