Webof the bonding between concrete and steel, is the same in the two materials. Both concrete and steel behave nearly elastically at low stresses; i.e., which are proportional to strain (corresponding to concrete strain of 0.0003~0.00045 and steel strain of 0.0012~0.0025). Since the stains are equal at a particular point, c = f c /E c is equal to ... WebMar 15, 2016 · I am trying to get a basic feel for what the Modulus of Elasticity means for different materials. My understanding is that since E = stress / strain, a higher E means a stiffer material, b/c it takes more force …
