Defining a layup using the lamination shorthand format

Use the Import Layup Using Shorthand Format option to quickly define a layup using the lamination shorthand format. You can specify a thickness and a material for all the plies.

You enter the shorthand notation in the Shorthand String box in the Shorthand Format dialog box. The shorthand notation has the following conventions:

• A ply layup is contained inside [] (square brackets).

• Ply angles are separated by / (forward slash).

• Ply groups are contained inside () (parentheses).

• Symmetry is indicated by the suffix _s (underscore and s). For a symmetric layup, the suffix is placed after the square brackets. For a symmetric group, the suffix is placed after the parentheses.

• The core ply is indicated by ʹ (apostrophe).

• A repeated layup, group, or ply is indicated by _# (underscore and number sign) where # indicates the number of repetitions.

• • (plus) and – (minus) in front of a number indicate the positive and negative angles.

Example:

When you enter [(+-45)_s(0/90)_3], your ply layup is composed of 10 plies and 5 groups as shown in the following graphic. Group 2 is a symmetric repeat of group 1. Groups 4 and 5 are non-symmetric repeats of group 3.

The following table shows additional examples of the shorthand format and the layups created using these formats.
