Shear Strength Tools
Energy and equipment corrections yield N60; vertical effective stress follows sample depth, groundwater depth, and bulk unit weight, then Idriss and Boulanger (2008) gives CN and (N1)60.
Open ToolRigidity / Deformation Tools
Small-strain shear modulus is obtained from the standard elastic wave relationship using shear wave velocity and either mass density or unit weight.

Why HS uses separate stiffness branches (E50, Eoed, Eur), how stress-level scaling and reference pressure work, and why calibration matters in settlement-dominated problems.
