Description

Section thickness (shell, membrane, and plane stress elements only).

Section thinning or thickening is defined as $STHIN = 1 - \frac{STH}{STH_{orig}}$ , where $STH_{orig}$ is the original thickness specified on the section definition for shell, membrane, and plane stress elements.

Section failure ratio across all the shell’s layers defined as $SFailRatio = \frac{numFailedLayers}{numTotalLayers}$ , where $numFailedLayers$ is the number of failed layers (a shell layer is considered failed when all of the section points in the layer failed), and $numTotalLayers$ is the total number of layers in the shell.

All section resultant components, both translational (forces) and rotational (moments).

Section force per unit width of component $n$ , $n = 1,2,3,4,5$ for conventional shells; $n = 1,2,3,4,5,6$ for continuum shells; $n = 1,2,3$ for beams and pipes.

Section moment per unit width of component $n$ , $n = 1,2,3$ .

Composite shell section orientations.

All section nominal strains, both translational and rotational (e.g., midplane strain and curvature in shells).

Section nominal strain component $n$ , $n = 1,2,3,4,5,6$ for shells; $n = 1,2,3$ for beams and pipes.

All average membrane and transverse shear stress components (shell elements only).

Average membrane or transverse shear stress component $n$ , $n = 1,2,3,4,5,6$ (shell elements only).

Description

Element stable time increment.

Element mass scaling factor.

Status of element (material failure with progressive damage, shear failure model, tensile failure model, porous failure criterion, brittle failure model, Johnson-Cook plasticity model, and VUMAT). The status of an element is 1.0 if the element is active, 0.0 if the element is not.

Current element volume. (Only available for continuum and structural elements not using general beam or shell section definitions.)

Forces at the nodes of an element from both the hourglass and the regular deformation modes of that element (negative of the internal forces in the global coordinate system).

Uniformly distributed gravity load.

Stagnation body force.

Uniformly distributed body force, including viscous body force.

Whole shell element maximum damage initiation output among all of the layers, all of the damage initiation criteria, and for fully integrated elements across all of the integration points.

This output variable is the same as DMICRTMAX output for solid and beam elements but complements the DMICRTMAX output variable for composite shell elements because it extracts the maximum damage initiation across all of the layers.

This output variable generates four element output quantities as follows:

EDMICRTMAXVAL outputs the maximum damage initiation value in the entire element.

EDMICRTLAYER outputs the layer number in which the maximum damage initiation value occurred.

EDMICRTTYPE outputs a value that represents the damage initiation criteria type that reached the

Description

maximum value in the element, as described in the DMICRTMAX output variable description.

EDMICRTINTP outputs the integration point number for which the maximum damage value occurred. For reduced-integration elements, the output value is one.

The maximum damage initiation output values are retained across the requested output frames until a higher maximum damage initiation value is computed.
