PSHELL (Shell Element Property)

Description

The PSHELL entry defines the membrane, bending, and transverse shear properties of shell elements (CTRIA3, CTRIAR, CQUAD4, and CQUADR entries).

Field	Definition	Type	Default
PID	Property identification number.	Integer > 0	Required
MID1	Material identification number for the membrane.	Integer > 0 or blank	Required
T	Membrane thickness for Ti on the connection entry.	Real or blank	Required
MID2	Material identification number for bending.	Integer ≥ -1 or blank	See Remarks 4, 5, and 6
THETA	Material property orientation angle in degrees.	Real or blank	See Remark 7
MCID	Material coordinate system identification number.	Integer ≥ 0	See Remark 7

Remarks

1. All PSHELL property entries must have unique identification numbers.
2. PSHELL entries may reference MAT1 material property entries.
3. Isotropic (MAT1) material properties may be referenced.
4. If only MID1 is specified, the elements referencing the PSHELL entry will have only membrane stiffness. If MID2 is specified in addition to MID1, the elements referencing the PSHELL entry will have bending and transverse shear stiffness in addition to membrane stiffness.
5. If MID2 specified, it must be the same as MID1.
6. The default for the MID2 field is MID1 when MID1 is a nonlinear material.
7. THETA/MCID is used only if field 8 of the CQUAD4 or CQUADR, or field 7 of the CTRIA3 or CTRIAR entry is blank. If field 5 of the PSHELL continuation is also blank, then THETA = 0.0 is assumed.
