Numerical Investigation of Flexural Properties of Sheet Metals Subjected to Embossing and Restoration Process

摘要

In this study, numerical simulations of flexural tests of sheet metals subjected to embossing and restoration process are carried out using LS-DYNA3D. Several models are created varying the number, position, and pitch of the emboss or restoration points. The emboss height and sheet thickness are also varied. Results show that improvement in rigidity of sheet metals can be optimized by taking into considerations several parameters as discussed in this paper.
