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
