@article{(Open Science Index):https://publications.waset.org/pdf/10800, title = {Effect of Friction Models on Stress Distribution of Sheet Materials during V-Bending Process}, author = {Maziar Ramezani and Zaidi Mohd Ripin}, country = {}, institution = {}, abstract = {In a metal forming process, the friction between the material and the tools influences the process by modifying the stress distribution of the workpiece. This frictional behaviour is often taken into account by using a constant coefficient of friction in the finite element simulations of sheet metal forming processes. However, friction coefficient varies in time and space with many parameters. The Stribeck friction model is investigated in this study to predict springback behaviour of AA6061-T4 sheets during V-bending process. The coefficient of friction in Stribeck curve depends on sliding velocity and contact pressure. The plane-strain bending process is simulated in ABAQUS/Standard. We compared the computed punch load-stroke curves and springback related to the constant coefficient of friction with the defined friction model. The results clearly showed that the new friction model provides better agreement between experiments and results of numerical simulations. The influence of friction models on stress distribution in the workpiece is also studied numerically}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {3}, number = {8}, year = {2009}, pages = {990 - 995}, ee = {https://publications.waset.org/pdf/10800}, url = {https://publications.waset.org/vol/32}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 32, 2009}, }
