Finite element analyses of real-time stability control in sheet forming processes
Article Abstract:
The cup forming process is simulated to analyze deformations during sheet metal processing. A thin steel blank is tested under constant boundary and binder conditions controlled by a closed-loop feedback algorithm. Finite element analysis was also performed to compare numerical and experimental data. Results show a springback error of less then 0.3% and thickness error of less than 0.5% between the two methods. The study also shows the advantage of using off-line detailed analyses to predict deformation.

Polycarbonate and a polycarbonate-POSS nanocomposite at high rates of deformation
Article Abstract:
A novel polymer nanocomposite was developed by blending impact-resistant Lexan 9034 PC with TriSilanolPhenyl-POSS., at a mass ratio of 95:5. The accurate predictions given by this model validate the assumption that the model framework is transferable to polymer nanocomposite materials systems, for the case where the nanoparticles are of order nanometer lengthscale in all dimensions and are well dispersed within the polymer.
