Mechanical characterisation of Duraform® Flex for FEA hyperelastic material modelling

The paper demonstrates how the measured tensile stress-strain curve can be transformed into appropriate hyperelastic material models employing the data curve fitting process in PTC Creo 2.0 Simulate software, and how these material models can be used practically to match user requirements for the laser sintered parts, leading to design optimisation for both bulky solid and lightweight lattice components. The paper concludes with a discussion examining the potential future direction of the research.
