calc_damping_from_stress_strain#

PySeismoSoil.helper_site_response.calc_damping_from_stress_strain(strain_in_unit_1: ndarray, stress: ndarray, Gmax: float) → ndarray[source]#

Calculate the damping curve from the given stress-strain curve.

Parameters:

  • strain_in_unit_1 (np.ndarray) – Strain array in the unit of 1. 1D numpy array.

  • stress (np.ndarray) – Stress. 1D numpy array

  • Gmax (float) – Maximum shear modulus, whose unit needs to be identical to that of the stress curve.

Returns:

damping – A 1D numpy array of damping ratios, in the unit of “1”.

Return type:

np.ndarray
