This command is used to construct an ElastomericX bearing element object in three-dimension. The 3D continuum geometry of an elastomeric bearing is modeled as a 2-node, 12 DOF discrete element. This elements extends the formulation of Elastomeric_Bearing_(Plasticity)_Element (or Elastomeric_Bearing_(Bouc-Wen)_Element) elements, however, instead of an user providing material models as input arguments, it only takes geometric and material properties of an elastomeric bearing as arguments. The material models in six direction are formulated within the element from input arguments. In addition to behavior captured by existing Elastomeric_Bearing_(Plasticity)_Element (or Elastomeric_Bearing_(Bouc-Wen)_Element) elements, this element can capture the following:
- Coupled bidirectional motion in horizontal directions
- Coupling of vertical and horizontal motion
- Cavitation and post-cavitation behavior in tension
- Strength degradation in cyclic tensile loading due to cavitation
- Variation in critical buckling load capacity due to lateral displacement
