The following sections describe the different matrices used by the COMBI250 element:
In the element coordinate system, the stiffness matrix is equal to:
where
| K1 to K6 = stiffness characteristics input on R command. |
In the element coordinate system, the viscous damping matrix is equal to:
where
| CV1 to CV6 = viscous damping characteristics input on R command. |
In the element coordinate system, the structural damping matrix is equal to:
where
| KIMAG1 to KIMAG6 = structural damping characteristics input on R command. |
