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 to produce the same amount of strain I was surprised to learn that Elasticty for concrete 24 GPa is an order of magnitude smaller than that of steel 200 GPa...
