Field |
Contents |
ID |
Unique ply identification number. No default (Integer > 0) |
MID |
Material identification number. Must refer to a MAT1, MAT2 or MAT8 bulk data entry. No default (Integer > 0) |
T |
Ply thickness. No default (Real > 0.0) |
THETA |
Ply orientation angle, in degrees, of the longitudinal direction relative to the x-axis of the material coordinate system associated with a given element. If no material coordinate system is specified for the element, the angle is measured relative to side 1-2 of this element. Default = 0.0 (Real or blank) |
SOUT |
Stress, Strain, and Failure Index output request. See comments 2 and 3. Default = NO (YES or NO) |
TMANUF |
Thickness of one manufacturable ply. Defines the thickness of one manufacturable ply. This parameter is used during sizing optimization to automatically create discrete design variables such that the thickness of the ply bundle is equal to a multiple of TMANUF. Default = blank (Real or blank) |
DID |
Draping identification number. Must refer to a DRAPE bulk data entry. Default = blank (Integer > 0) |
ESID# |
Element SET identification numbers. Lists the elements for which this PLY card is defined. A minimum of one ESID# should be specified. No default (Integer > 0) |
Comments
| 1. | The PLY card is used in combination with the PCOMPP and STACK cards to create composite properties through the ply-based definition. |
| 2. | Stress, Strain and Failure Index output for the PLY is activated by setting SOUT to YES. In addition, the CFAILURE I/O Option should be defined. Failure Index output for PLY’s also requires that the FT and SB fields be defined on the corresponding PCOMPP entries, and that stress/strain allowables on the referenced materials are defined. |
| 3. | An additional piece of information available with ply results is "failure index for the element," which is the maximum of failure indices for individual plies in this element. Only the plies with SOUT set to YES are considered in the evaluation of this maximum. |
| 4. | This card is represented as a ply in HyperMesh. |
