ID |
Each PFATSMW card must have a unique ID. This ID may be referenced from a FATDEF definition. No default (Integer > 0) |
BRATIO |
Critical bending ratio Default = 0.5 (Real > 0.0) |
TREF |
Reference thickness for thickness effect consideration (Comment 1). Default = 1.0 (Real > 0.0) |
TREF_N |
Exponent for the thickness effect consideration (Comment 1). Default = 0.2 (Real ≥ 0.0) |
| 1. | TREF is used to define the reference thickness for thickness effect consideration. If the thickness of a shell (T) is greater than the specified value (TREF), and the THCKCORR field on the FATPARM entry is set to YES, then the thickness effect is included by increasing the stress ( ) based on the following calculation: |
