WebMar 30, 2016 · E' is the 'drained' Young's modulus (also noted as E d ), which is just the stiffness in the graph above because it is a drained test. Moreover, you wouldn't be able to get E u (the 'undrained' Young's modulus) from the above test because it is not an undrained test. E'50 is the E50 I referred to in my previous post. WebMay 21, 2024 · The oedometric Young's modulus (E oed) is just the constrained modulus (M). Supposing you want an elastic modulus (which I presume is the case given the large coefficients others have pointed out), and it is for a homogenous isotropic material, you derive M from your other stiffnesses using Poisson's ratio.
