The draping simulation approach has the following limitations:
The surfaces to be draped must be smooth. No sharp edges are allowed.
The draping procedure does not change mechanical properties of the ply by default. However, mechanical properties can be altered if a shear-dependent material is defined. For more information, see Variable Material Data in Composite Analyses in the ACP User's Guide.
Draping parameters, such as mesh size and seed point, will significantly effect the draping results. Be sure to verify the results carefully.
Ply thickness does not automatically change as a result of a draping procedure. A thickness correction can, however, be activated in the modeling ply properties.
It is assumed that fabric transverse direction is initially perpendicular to the principal direction 1.
The fiber slippage is a phenomenon that takes place after the locking limit and is noticeable only at relatively high deformation levels. The fiber slippage is not considered in this draping approach.
It is known that some geometries can lead to flawed or deficient results, for example draping across a complete cylinder. This issue can be rectified by subdivision of the draping geometry.
