Element Output

The relative displacements and rotations corresponding to the forces and moments below are chosen by requesting the corresponding “strains.” Elastic and plastic strains are available. For a spud can the vertical (plastic) embedment since the start of the analysis is given by PE11; the total vertical embedment is available as PEEQ.

JOINT2D

S11: Total direct force in the first local direction.
S22: Total direct force in the second local direction.
S12: Total moment about the third local direction.

JOINT3D

S11: Total direct force in the first local direction.
S22: Total direct force in the second local direction.
S33: Total direct force in the third local direction.
S12: Total moment about the third local direction.
S13: Total moment about the second local direction.
S23: Total moment about the first local direction.

Nodes Associated with the Element

Two nodes.
