Element types

SPRINGA Axial spring between two nodes, whose line of action is the line joining the two nodes. This line of action may rotate in large-displacement analysis.
SPRING1^(S) Spring between a node and ground, acting in a fixed direction
SPRING2^(S) Spring between two nodes, acting in a fixed direction

Active degrees of freedom

SPRINGA: 1, 2, 3. The translational degree of freedom in the 3-direction is not activated in an ABAQUS/Standard analysis if both nodes of the element are connected to two-dimensional entities such as two-dimensional analytical rigid surfaces, two-dimensional beam elements, etc.

SPRING1 or SPRING2: 1, 2, 3, 4, 5, or 6. If you specify a local orientation for the spring, these are local degrees of freedom. Otherwise, these are global degrees of freedom.

Additional solution variables

None.

Nodal coordinates required

SPRINGA: , ,

SPRING1 or SPRING2: None needed, since there is no geometry associated with these elements
