Numerical simulation of hot imprint process of periodical lamellar microstructure in to polycarbonate

摘要

The aim of this paper was to create finite element model of the hot imprint process for analysis of the heating, imprinting and demolding steps. Polycarbonate was modeled as elasto-plastic material, because it was analyzed below glassing temperature. In general, the simulation model and numerical results provide a useful understanding of the fundamental formation mechanism during the hot imprint process and serve as a useful guide for specifying the optimal processing conditions for variety of hot imprint applications.
