Finally , the prediction of the deformed shape is discussed in regards to bulging simulation : to improve the accuracy of the calculated final shape , a novel extension of the model relying on the modified stiffness of inactive upper layers is proposed and the experimentally observed bulging could be reproduced in the finite element model .
