Contents |
MID |
Unique material identification number. No default (Integer > 0) |
E |
Young’s Modulus. No default (Real) |
NU |
Poisson’s ratio. Default = blank (-1.0 < Real < 0.5 or blank) |
Y |
Yield stress. No default (Real) |
K |
Strength coefficient. No default (Real or blank) |
n |
Strain hardening component. No default (Real or blank) |
EPS0 |
Pre-strain coefficient. No default (Real or blank) |
R0, R45, R90 |
Lankford coefficients. No default (Real) |
TABLEID |
Table ID for stress-strain curve using a TABLES1 entry. No default (Integer > 0) |
| 1. | This entry is only valid with a @HyperForm statement in the first line of the input file. |
| 2. | The TABLEID and the corresponding curve are required only when material data is specified with a stress-strain curve. For such case, material parameter such as K, n and EPS0 are extracted from the stress strain curve. |
