Parameter	Description
IPRO	reference number
Xlo	element length
Mlo	linear mass
DiamH	Hydraulic diameter
Cd	normal drag coefficient
Cm	normal inertia coefficient
Cdl	tangent drag coefficient
Cml	tangent inertia coefficient
EAs	axial stiffness for static analysis (istep 0)
EAqs	axial stiffness for quasi-static analysis (istep > 0)
EAd	dynamic axial stiffness
BLK	breaking load
Kr_inf	see note. Default value=21
ML_lim	see note. Default value=10
Coef_kr	see note. Default value=14/40

Note

If EAd = 0, the breaking load must be given. The dynamic axial stiffness will then be automatically evaluated as following :

Tmean is the mean load at the end of the quasi-static calculations

ML = 100*Tmean/BLK

then EAd = Kr*BLK

with Kr = Kr_inf if ML ML_lim Kr = Kr_inf + coef_kr*(ML ML_lim) if ML ML_lim **
