Detailed Description
Four-node quadrilateral element, which uses a bilinear isoparametric formulation with enhanced strain modes.
Member Function Documentation
§ getInitialStiff()
|
virtual |
HERE
Implements XC::Element.
§ getMass()
|
virtual |
Returns the mass matrix.
Returns the mass matrix. The element is to compute its mass matrix based on the original location of the nodes and the current trial response quantities at the nodes.
\[ //! M_e= {\frac{\partial I_i}{\partial \ddot U} \vert}_{U_{trial}} //! \]
Reimplemented from XC::Element.
§ getResistingForce()
|
virtual |
Returns the resisting force vector for the element.
This is equal to the applied load due to element loads minus the loads at the nodes due to internal stresses in the element due to the current trial displacement, i.e.
\[ R_e= P_{e} - {R_e}(U_{trial}) \]
Implements XC::Element.
§ getResistingForceIncInertia()
|
virtual |
Returns the resisting force vector including inertia forces.
Returns the action of the element over its attached nodes.
Returns the resisting force vector for the element with inertia forces included. This is equal to the applied load due to element loads (loads set using addLoad(), minus the loads at the nodes due to internal stresses in the element due to the current trial response quantities, i.e.
\[ R_e = P_e - I_e (\ddot U_{trial}) - R_e(\dot U_{trial}, U_{trial}) \]
Computes damping matrix.
Reimplemented from XC::Element.
§ getTangentStiff()
|
virtual |
Return the tangent stiffness matrix.
To return the tangent stiffness matrix. The element is to compute its stiffness matrix based on the original location of the nodes and the current trial displacement at the nodes.
\[ K_e = {\frac{\partial f_{R_i}}{\partial U} \vert}_{U_{trial}} \]
Implements XC::Element.
§ update()
|
virtual |
Updates the element state.
This method is invoked after the response quantities have been updated in the Domain, but not necessarily committed, e.g. during a non-linear Newton-Raphson solution algorithm. To return \(0\) if successful, a negative number if not. This base class implementation returns 0.
Reimplemented from XC::Element.
