structure beam list command

Syntax

structure beam list keyword <range>

Primary keywords:

apply    element-type    force-node    group    information    length    model    plastic-state    plastic-strain    plastic-stress    plastic-stress-bounds    property    system-local

List properties and responses of beam elements in the range. If no keyword is given, the default output of the command is that associated with the information keyword.

apply

Uniform applied distributed load acting on the element.

element-type

finite element type

force-node <keyword>

generalized nodal forces (force and moment) acting on the element. These are the generalized forces exerted by the nodes on the element.

local

Express listed values in the element coordinate system (the default).

global

Express listed values in the global coordinate system.

group <slot s >

group assignment(s). If slot is specified, then list the group assignment, if any, in slot s.

information

general element information: nodal connectivity, centroid, surface area, volume, and hide/select status.

length

length of the element

model

constitutive model

plastic-state <integration-point ind > (3D ONLY)

Plasticity state indicators for beam-type elements with a plastic material model. Each beam-type element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its plasticity state. The plasticity states at all integration points are listed, unless integration-point is specified. The integration point locations are shown here and here. The plasticity states of the plastic constitutive models can be listed by the structure beam cmodel list states (or pile) command.

plastic-strain <integration-point ind > (3D ONLY)

Strain (axial component \(\varepsilon_{xx}\) in element coordinate system) for beam-type elements with a plastic material model. Each beam-type element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its axial strain. The axial strain at all integration points is listed, unless integration-point is specified. The integration point locations are shown here and here. The strain can be initialized with the struct.beam.plastic.ipstrain function.

plastic-stress <integration-point ind > (3D ONLY)

Stress (axial component \(\sigma_{xx}\) in element coordinate system) for beam-type elements with a plastic material model. Each beam-type element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its axial stress. The axial stress at all integration points is listed, unless integration-point is specified. The integration point locations are shown here and here.

plastic-stress-bounds (3D ONLY)

Minimum and maximum axial stress for beam elements with a plastic material model.

property <integration-point ind > keyword <scaled b >

The properties consist of constitutive model properties, and additional properties of beam-type elements. The constitutive model properties are listed by specifying the constitutive model property name; these names are not listed here. Elastic-plastic constitutive model properties are stored at each integration point. Such properties are the same at all integration points, except for the softening properties of the strain-softening/hardening Mohr Coulomb constitutive model. The value at a particular integration point is listed by specifying the integration-point keyword — the integration point locations are shown here and here.

Scaled properties are returned if the scaled keyword (FLAC2D ONLY) is set to true (the default is false). If the property cannot be scaled, an error is emitted.
