32.8.2 Tube support element library

Product: Abaqus/Standard  

Overview

This section provides a reference to the tube support elements available in Abaqus/Standard.

Element types

ITSUNIUnidirectional tube support element
ITSCYLCylindrical geometry tube support element

Active degrees of freedom

1, 2, 3, 4, 5, 6

Additional solution variables

None.

Nodal coordinates required

X, Y, Z

Element property definition

Input File Usage:          
*ITS

Element-based loading

None.

Element output

S11

Total direct force in the element.

S12

Tangential (shear) force component, caused by friction, in the plane of the cross-section of the tube.

S13

Tangential (shear) force component, caused by friction, parallel to the axis of the tube.


The force in the spring link and the force in the dashpot are defined as generalized substresses and, therefore, are available as substress selections in the output options, as follows:

SS1

Force in the spring link.

SS2

Force in the dashpot.


The relative axial and tangential displacements corresponding to the forces above are chosen by requesting the corresponding “strains,” except that “strain” component E13 is not defined in element type ITSCYL.

The relative tangential (shear) displacement components during slip are available as “plastic strain” components PE12 and PE13. The “equivalent plastic strain” is defined in these elements as

where and are the two relative tangential displacement components.

Nodes associated with the element

ITSUNI: Two nodes—one on the axis of the tube and one equidistant between the two parallel support plates.

ITSCYL: Two nodes—one on the axis of the tube and one at the center of the hole in the support plate.
