4.14.4.1. PySimple1 Material¶

uniaxialMaterial('PySimple1', matTag, soilType, pult, Y50, Cd, c=0.0)

This command is used to construct a PySimple1 uniaxial material object.

`matTag` (int)	integer tag identifying material
`soilType` (int)	soilType = 1 Backbone of p-y curve approximates Matlock (1970) soft clay relation. soilType = 2 Backbone of p-y curve approximates API (1993) sand relation.
`pult` (float)	Ultimate capacity of the p-y material. Note that “p” or “pult” are distributed loads [force per length of pile] in common design equations, but are both loads for this uniaxialMaterial [i.e., distributed load times the tributary length of the pile].
`Y50` (float)	Displacement at which 50% of pult is mobilized in monotonic loading.
`Cd` (float)	Variable that sets the drag resistance within a fully-mobilized gap as Cd*pult.
`c` (float)	The viscous damping term (dashpot) on the far-field (elastic) component of the displacement rate (velocity). (optional Default = 0.0). Nonzero c values are used to represent radiation damping effects
