This paper studies the formability of functional composite structures, consisting of a metal substrate, insulating plastic
foils, flat copper conductors and printable conductive polymers. The aim is the production of smart components in a
sheet metal hydroforming process. In addition to their mechanical properties, these components can also transfer energy
and data. Conventional boundaries between mechanics and electronics will be relaxed expediently.
The challenge of this study is the design of the forming process, so that all elements of the multi-layer composites will
withstand the process conditions. In this context, an analytical method for estimating the formability of these smart
components is presented. The main objectives are the definition of basic failure modes and the depiction of the process
limits.
