pressureDependMultiYield relation to Yang, Elgamal and Parra

[mlw]

Hi all,

Could anyone please tell me how the pressureDependMultiYield input parameters (i.e. contrac, dilat1 and 2, and liquefac1, 2, and 3) relate to the equations presented in Yang, Elgamal and Parra (2003) "Computational model for cyclic mobility and associated shear deformation"

For example: is dilat1 equal to d1 and dilat2 equal to d2 in Equation 8, is contrac developed from c2 in Equation 7, is liquefac2 related to c1 in Equation 7, and is liquefac3 equal to po' on Fig 3.
Are these correct?

Thank you for your time,

mlw
