STRESS PARAMETER FILE Z88I3.TXT
Mind the following format:
[Long] = 4 bytes Integer number
File only consists of
only one line:
1st value: For isoparametric elements No. 1,
7, 8, 10, 11, 12, 14, 15, 16, 17, 18, 19, 20:
Value of the integration
order INTORD [Long]
Valid is:
0 = Calculation of stresses
into the corner nodes, von Mises stress calculation not possible.
For isoparametric
elements No.1, 7, 8, 10, 11, 12, 19, 20:
1, 2, 3 or 4 (i.e. N*N) =
Calculation of stresses into the Gauss points. Von Mises stress
calculation is possible. A good value is 3 (= 3*3 Gauss points). For element
type No.1 and No.20 a value of 2 could be fine. For type No.19, a value of 4 (=
4*4 Gauss points) is recommended.
For isoparametric
elements No.14, 15, 18:
3, 7 or 13 (i.e. N) =
Calculation of stresses into the Gauss points. Von Mises stress
calculation is possible. A good value is 7 (= 7 Gauss points). For type No.18,
a value of 3, i.e. 3 Gauss points, will do.
For isoparametric
elements No.16, 17:
1, 4 or 5 (i.e. N) =
Calculation of stresses into the Gauss points. Von Mises stress
calculation is possible. A good value is 5 (= 5 Gauss points). For element type
No.17 a value of 1 could be fine.
This 1st value has no
meaning for element types No.2, 3, 4, 5, 6, 9 and 13. However, please enter a
value of 1 to satisfy the filechecker Z88V.
2nd value: For
the plane stress elements No.3, 7, 11 and 14: KFLAG [Long]
0 = standard stress
calculation
1 = additional calculation of the radial and tangential stresses
3rd value: Choice of the reduced stress
hypothesis: ISFLAG [Long]
0 = no calculation of the
reduced stresses
1 = von Mises stresses
Example 1: The stress processor Z88D is
supposed to calculate for a structure of Plane Stress Elements No.7 the stresses for every finite
element into 3*3 Gauss points: INTORD = 3. In addition to this calculation of
standard-stresses a calculation of radial and tangential stresses is supposed
to be run, KFLAG = 1. Furthermore compute von Mises stresses: ISFLAG =
1. Thus : 3 1 1
Example 2: The stress processor Z88D is supposed to compute only the stresses of the corner nodes for every finite element No.7. Only standard-stress calculation, thus KFLAG = 0. Do not compute von Mises stresses, thus ISFLAG = 0. Thus : 0 0 0
