Input file
Parameters defining the type of constitutive law
| Line 1 (2I5, 60A1) | |
|---|---|
| IL | Law number |
| ITYPE | 5 |
| COMMENT | Any comment (up to 60 characters) that will be reproduced on the output listing |
Integer parameters
| Line 1 (I5) | |
|---|---|
| ISOL | = 0 : use of total stresses in the constitutive law |
| = 1 : use of effective stresses in the constitutive law | |
Real parameters
| Line 1 (2G10.0) | |
|---|---|
| E | YOUNG’s elastic modulus |
| ANU | Area of the TRUSS elements |
Stresses
Number of stresses
2
Meaning
The stresses are the PIOLA-KIRCHOFF number 2 Normal Force in the TRUSS element.
| SIG(1) | $N_{PK2}$ at node I |
| SIG(2) | $N_{PK2}$ at node J |
N.B. SIG(1) = SIG(2)
State variables
