Embossing process is a prevalent method in enhancing flexural rigidity of sheet metal. Also, embossed sheets could realize multifunction due to their good performance in heat radiation, energy absorption and sound insulation etc..
It is well known that mechanical properties of plain sheets depend on aggregate texture. Additionally, when a periodic convex-concave structure would be planted through embossing process, it has been confirmed a new apparent anisotropy of the embossed sheet depends on both aggregate texture and embossing periodic structures.
In this study, FE simulations of hole-expansion for embossed sheets were conducted. The simulations were separated into two steps. Embossing processes were simulated firstly in order to obtain an embossed model. Next, hole-expansions were simulated using embossed models with and without work hardening effect derived from embossing process. From the numerical results, deformation behavior of embossing structure during hole-expansion was investigated. Moreover, the effect of work hardening was also discussed.
