Description

Generates animation files containing shell tensor data for a specified result.

Format

/ANIM/SHELL/TENS/Restype/Keyword5/Keyword6

Data	Description
Restype	Output tensor: STRESS - Stress tensor
	STRAIN - Strain tensor
	EPSDOT - Strain rate tensor
Keyword5	Result type or location: MEMB - Membrane
	BEND - Bending
	UPPER - Upper layer
	LOWER - Lower layer
	N - Layer number N
	ALL - All the layers
Keyword6	Result type or location: NIP - Number of integration points through layer, N (Comment 6)
	ALL - All the integration points (NIP) through the layer, N
	UPPER - Upper integration point (NIP) of the upper layer, N
	LOWER - Lower integration point (NIP)of the lower layer, N

Comments

1.	Stress and strain tensor are output in the elemental coordinate system.

2.	Strain tensor is output only if Istrain =1 in shell property (/PROP/TYPE1, /PROP/TYPE10, /PROP/TYPE11, /PROP/TYPE16 and /PROP/TYPE17), except for material laws 15, 19 and greater than or equal to 25 (in these cases strain tensor is output irrespective of Istrain flag value).

3.	For STRAIN, UPPER gives + (t/2)k and LOWER gives - (t/2)k.

With being the strain, t is the thickness and k is the curvature. For EPSDOT, strain and curvature are replaced by strain rate and curvature rate.

4.	The stress tensor output at UPPER/LOWER (and at N) is available when global integration is not used (N>0 defined in property). In the case of using global integration (N=0), then RADIOSS will output the stress at the midplane, even if the stress at UPPER/LOWER is requested.

The stress at UPPER/LOWER is the stress at the upper most / lower most integration point and not an interpolated value based on curvature like the strain.

5.	Options /ANIM/SHELL/TENS/STRESS/MEMB and /ANIM/SHELL/TENS/STRESS/BEND are generalized forces (mean values through thickness) per element. For full-integrated element, mean value of 4 Gauss points of the shell surface is calculated. Shell stress can be considered at the center of the element.

6.	This option is available only if Keyword5 = N (for each defined layer N allows to compute shell tensor within each integration point NIP of layer N). This option is only available for property set 51 (/PROP/TYPE51 with multiple integration points through each layer).

Nevertheless, Keyword5=ALL combined with Keyword6=ALL is allowed.
