Mesh-free methods are particularly suitable for material forming simulations, where application of the finite element method can be troublesome due to mesh distortion. This work involves the simulation of stretch blow moulding which is the main manufacturing process used to produce PET drink bottles, a market estimated to grow to $45 billion by the end of 2021. Due to the large deformation involved in the process, conventional finite element simulations can suffer from mesh related issues. This can require a re-meshing procedure and possible solution degradation. In this paper a Lagrangian mesh-free formulation is employed. Initial results confirm the effectiveness of mesh-free methods in simulating the free-blow process.
