4.2.6.9. YamamotoBiaxialHDR Element¶

This command is used to construct a YamamotoBiaxialHDR element object, which is defined by two nodes. This element can be used to represent the isotropic behavior of high-damping rubber bearing in the local y-z plane.

element('YamamotoBiaxialHDR', eleTag, *eleNodes, Tp, DDo, DDi, Hr, <'-coRS`, cr, cs>, <'-orient`, *vecx, *vecyp>, <'-mass`, m>)

`eleTag` (int)	unique element object tag
`eleNodes` (list (int))	a list of two element nodes
`Tp` (int)	compound type = 1 : X0.6R manufactured by Bridgestone corporation.
`DDo` (float)	outer diameter [m]
`DDi` (float)	bore diameter [m]
`Hr` (float)	total thickness of rubber layer [m] Optional Data
`cr` `cs` (float)	coefficients for shear stress components of tau_r and tau_s
`vecx` (list (float))	a list of vector components in global coordinates defining local x-axis (optional)
`vecyp` (list (float))	a list of vector components in global coordinates defining vector yp which lies in the local x-y plane for the element.
`m` (float)	element mass [kg]
