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 $iNode $jNode $Tp $DDo $DDi $Hr <-coRS $cr $cs> <-orient <$x1 $x2 $x3> $y1 $y2 $y3> <-mass $m>

$eleTag unique element object tag
$inode $jnode end nodes
$Tp compound type
= 1 : X0.6R manufactured by Bridgestone corporation.
$DDo outer diameter [m]
$DDi bore diameter [m]
$Hr total thickness of rubber layer [m]
Optional Data
$cr $cs coefficients for shear stress components of <math>\tau_{r}</math> and <math>\tau_{s}</math>
$x1 $x2 $x3 vector components in global coordinates defining local x-axis
$yp1 $yp2 $yp3 vector components in global coordinates defining vector yp which lies in the local x-y plane for the element
$m element mass [kg]


1) The valid queries to a YamamotoBiaxialHDR element when creating an ElementRecorder object are 'globalForce', 'localForce', 'basicForce', 'localDisplacement' and 'basicDeformation'.
