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 $iNode $jNode $Tp $DDo
$DDi $Hr <-coRS $cr $cs> <-orient <$x1 $x2 $x3> $y1 $y2
$y3> <-mass $m>
eleTag
|
unique element object tag |
|
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 |
|
|
coefficients for shear stress components of \(\tau_{r}\) and <math>_{s}</math> |
|
vector components in global coordinates defining local x-axis |
|
vector components in global coordinates defining vector yp which lies in the local x-y plane for the element |
m
|
element mass [kg] |
NOTES:
- The valid queries to a YamamotoBiaxialHDR element when creating an ElementRecorder object are ‘globalForce’, ‘localForce’, ‘basicForce’, ‘localDisplacement’ and ‘basicDeformation’.
