Deep draw induced wrinkling of engineering fabrics

Deep-draw experiments are performed on both glass and carbon fabric to better understand the origin of wrinkle growth during complex forming assess accuracy, robustness computational cost simulations engineering fabrics. During experiments, shape deformed blanks is digitised using two different non-contact measurement techniques (Structured Light Scanning Photogrammetry). The resulting digital point clouds permit detailed analysis shows that perform well in predicting very behaviours sensitivity formation initial conditions demonstrated direction process shown influence draw-in; an observation could potentially be used mitigate draw-in actual processes.
