MIDi Material ID for the ply defined via the previous IDi field. Currently MAT1, MAT9, MAT9ORT, and MATUSR materials are supported.

No default (Integer > 0)

Ti Defines the user-defined ply thickness of the ply specified via the IDi field. 6

No default (Real > 0.0)

THETAi Orientation angle of the ply within the ply plane. 4 5

Default = 0.0 (Real)

1. The global Ply ID should be unique with respect to other ply's on this PCOMPLS entry.
2. The PCOMPLS entry is only supported for first order CHEXA and CPENTA elements.
3. The Global Ply IDs uniquely identify ply's across all PCOMPG and PCOMPLS entries.
4. The thickness direction of the composite element by default starts from face G1-G2-G3-G4 to face G5-G6-G7-G8 of the solid element. Ply numbering also follows this thickness direction. This is used to only determine the direction of the local Z axis of the plies. The local Z-axis of each ply is perpendicular to the ply plane and aligned to the thickness direction. The X-axis of the coordinate system defined via CORDM (basic system, if blank) is projected onto the ply plane to determine the local X axis for the ply. The local Y-axis is then determined by the cross-product of the local X and Z axes.
5. The orientation angle is measured in the positive counter clockwise direction from this projected X-axis about the local Z axis of the ply.
6. The actual ply thicknesses depend on the actual total geometric thickness of the solid element:(1)
${T}_{actual}^{ply_i}={T}_{actual}^{e}*\left(\frac{{T}_{i}}{{T}_{1}+{T}_{2}+....+{T}_{N}}\right)$
Where,
${T}_{actual}^{ply_i}$
Actual thickness of the Ply “I”
${T}_{actual}^{e}$
Actual (or geometric) thickness of the composite element
${T}_{i}$
User-defined ply thicknesses via the Ti field
