WARNING: T2085
|
EXCESSIVE ERROR IN MATERIAL CONSTANT ESTIMATION (XXX.X PERCENT)
|
|
|
Cause:
|
A
MATHP Bulk Data entry requested the generation of hyperelastic material constants using experimental data specified on
TABLES1 Bulk Data entries. The Root-Mean-Square (RMS) error of calculated stress from the estimated material constants to the experimental stress was greater than 10%.
|
|
|
Action:
|
If the error specified in parentheses is acceptable, no further action is required. Otherwise, perform the following actions:
- Check the experimental data and make sure it is in the correct format as specified on the MATHP entry in the Autodesk Nastran Reference Guide.
- Adjust the NA polynomial function setting (for TAB1, TAB2, TAB3, and TAB4 specification) and/or the ND polynomial function setting (for TABD specification) on the MATHP entry.

Remarks:

See Autodesk Nastran Reference Guide, Section 4,
Bulk Data, for entry format.
