Some Aspects of Optimal Design of Neuro-Mechanical Shape Memory Devices
(English)Manuscript (preprint) (Other academic)
Neuro-Mechanical Shape Memory Devices (NMSMDs) are a new type of active mechanical systems designed to take on prescribed shapes when subjected to a certain input stimuli. In an earlier paper we derived a mathematical model for NMSMDs and posed an optimization problem for finding system parameters that would result in an NMSMD with a certain desired behavior. The optimization problem was highly nonlinear and non-convex, making it difficult to find good solutions. In this paper, through using a numerical example, we show that these difficulties can be alleviated by a new formulation of the original optimization problem. However, it is also shown that, due to the possible existence of multiple equilibrium points for the governing equations of NMSMDs, solutions to the new optimization problem must be carefully validated.
