`structure geogrid list`

command

Syntax

- structure geogrid list keyword <range>
Primary keywords:

apply coupling depth-factor element-type group information force-node property resultant stress stress-principal system-local

List properties and response of each geogrid element in the range.

- apply
uniform applied pressure acting on the element

- coupling
Information about the shear coupling springs connecting the liner to the zones. The confining stress, displacement, yield state, and direction is given.

- depth-factor
depth factor used during stress recovery

- element-type
finite element type used

- group <slot s >
list the group assignment(s) of this element. If slot is supplied, list the group assignment for this element, if any, in slot s.

- information
Lists general element information, including id and component-id numbers, connected nodes, centroids, surface area, volume, and the hide and select status.

- force-node keyword
List nodal forces. By default, components are displayed in terms of the element local coordinate systems. These are the forces exerted by the nodes on the element.

- local
List forces in terms of the element local coordinate system (the default).

- global
List forces in terms of the global coordinate system.

- property
- density
density, \(ρ\)

- thickness
geogrid thickness

- thermal-expansion
thermal expansion coefficient

- anisotropic-membrane
anisotropic membrane material-stiffness coefficients { \(c_{11}\), \(c_{12}\), \(c_{13}\), \(c_{22}\), \(c_{23}\), \(c_{33}\) }

- anisotropic-bending
anisotropic bending material-stiffness coefficients { \(c_{11}\), \(c_{12}\), \(c_{13}\), \(c_{22}\), \(c_{23}\), \(c_{33}\) }

- material-x
Vector used to determine the local X direction of the material coordinate system.

- isotropic
isotropic material properties: \(E\) and \(v\), where \(E\) is Young’s modulus \([F/L^2\)\(]\) and \(v\) is Poisson’s ratio

- orthotropic-membrane
orthotropic membrane material-stiffness coefficients { \(c_{11}\), \(c_{12}\), \(c_{22}\), \(c_{33}\) }

- orthotropic-bending
orthotropic membrane material-stiffness coefficients { \(c_{11}\), \(c_{12}\), \(c_{22}\), \(c_{33}\) }

- coupling-cohesion
coupling spring cohesion (stress units)

- coupling-friction
coupling spring friction angle (degrees)

- coupling-stiffness
coupling spring stiffness per unit area

- slide
large-strain sliding flag

- slide-tolerance
large-strain sliding tolerance

- resultant <nodes>
all eight stress resultant quantities last calculated with the

`structure geogrid recover resultants`

command. If the nodes keyword is given the values of these quantities is supplied at each node of the element, in addition to the value at the element centroid.

- stress <nodes>
the stress state calculated with the

`structure geogrid recover stress`

command. If the nodes keyword is given the values of these quantities is supplied at each node of the element, in addition to the value at the element centroid.

- stress-principal <nodes>
principal stresses calculated with the

`structure geogrid recover stress`

command. If the nodes keyword is given the values of these quantities is supplied at each node of the element, in addition to the value at the element centroid.

- system-local
element local coordinate system
