TH Output Keyword & Variables

Table of Available Variables - Part 2

Output for 3-node Shells

Comments

1. Available names are listed in the two tables above.

   In the first table, TH-variables are listed. If a TH-variable is requested, this variable is written.

   In the second table, other variable groups are listed. If a variable group is requested, all the associated TH-variables are written at once.

2. The value for EPSD (equivalent strain rate) is only computed in case of the strain rate filtering is asked for the material law. It is available for Laws 2, 15, 25, 27, 36, 44 and 48.
3. Shear strains are ${\gamma }_{\mathit{ij}}={\epsilon }_{\mathit{ij}}+{\epsilon }_{\mathit{ji}}=2{\epsilon }_{\mathit{ij}}$ .
4. For /MAT/LAW25 (COMPSH), the output EMIN and EMAX corresponds to minimum plastic work and respectively maximum plastic work.
5. The value of EPSD will be computed only in case of strain rate filtering is asked for in the material law.
6. Output for subset or part (for /TH/SH3N or /TH/SHEL only):

   NFAIL is the total number of failed layers

   PFAIL is the percentage of failed layers

   FAIL_D1 is the number of layers which reached the failure level in direction 1

   FAIL_D2 is the number of layers which reached the failure level in direction 2

   FAIL_EN is the number of layers which reached the failure level in plastic work

   WPLAYJJ is the plastic work for layer JJ

   HE: global hourglass energy with visco-energy added for numerical stabilization if QBAT and QEPH shell formulations (I_shell =12 or 24) are used (refer to the /PROP/TYPE1 (SHELL))

7. OFF:
   • 0.0 deleted element
   • 1.0 active element
   • 2.0 (shells / solids): active element using small strain
   • Negative value -1/-2 when the element is on stand-by due to rigid body

   Some intermediate values can be found during few cycles before element deletion (progressive reduction of off during a few cycles applies as a multiplicative factor to the stress, so that the stress is progressively vanished and the element is deleted after ~ 10 cycles). This process applies to some element types, but not all.

8. Skew system is used to determine coordinate system to output generalized (averaged through the thickness) stress tensor components and moments F1, F2, F12, Q1, Q2, M1, M2, and M12. By default, the skew system is coincident with elemental coordinate system. When the skew system is specified, then X- axis of the system is projected to the element plane to obtain direction 1 of the local coordinate system. Direction 2 is obtained by rotation of the first axis by 90 degrees. Angle between direction 1 and X- direction of the elemental coordinate system is fixed a does not change during simulation. Components F1, F2, F12, Q1, Q2, M1, M2, and M12 are projected to this local coordinate system.
9. SX_JJ, SY_JJ, SXY_JJ, SYZ_JJ, and SZX_JJ (JJ=1,99) are the components of the stress matrix expressed in in the local skew per layer through element thickness.

   The local skew is elemental coordinate system for any isotropic material law as well as material laws 19, 27, and 32. Local skew is the orthotropic material coordinate system in case of orthotropic material laws 15, 25, and all orthotropic material laws higher than 28. LAW1 has only global integration or membrane formulations (with NP=1 in /PROP/SHELL). Therefore, only global stress with components (F1, F2, F12, ...) are available.

10. Set I_strain=1 in shell property is needed for strain output.
