title = "Optimisation of hot-forming process through in-plane constraints: Numerical and experimental studies",
abstract = "The hot-forming process for thermoplastic composites is a very promising fabrication route for high volume applications. Reliable and fast numerical tools are needed to optimise the forming process and to support industrial exploitation. This paper presents the experimental validation of a finite element-based optimisation routine, which is used to minimise the local fibre shear angle by adjusting the in-plane constraints used to control material draw-in. A non-orthogonal constitutive model is used to simulate the behaviour of the thermoplastic composite material using a finite element approach, which is coupled with a genetic algorithm to optimise forming parameters, such as clamp location, clamp length and clamping force. A double-dome benchmark geometry is used to validate the finite element approach, using grid-strain analysis to compare local shear angles and the perimeter shape of the blank.",
