Simcenter 3D enables you to specify a draping start point and an initial draping direction, or to pick a seed curve. You can then coarsen or refine the drape mesh size and view the ply flat pattern. Ply materials You can combine fiber and matrix properties to create ply materials, which can be used in the laminate stack just like standard Simcenter 3D materials. Microme chanics theories allow you to create ply materials with the following types of fibers: • Unidirectional • Woven (you can specify the angle between the warp and weft fibers) • Particulate • Randomly oriented short fiber A core ply material allows you to define 3D layup inflation Dynamic simulation thickness-dependent shear stress limits.

Laminate stiffness matrices (A, B, D and S) can be displayed in both Microsoft Excel and text formats. Similarly, equivalent engineering con- stants can also be displayed, enabling you to assess the characteristics of your laminate prior to solution.
