Benchmarking case for validation of draping software

� The mapping approach severely fails in predicting the fiber reorientation that occurs during forming.

� The mechanical simulation approach gives a fairly good prediction of the fiber reorientation and seems the most promising technique in having good draping simulations.

� The test results present a simple and distinctive benchmark for validation of any draping software
