Morphing Wing I - finite element modelling of a NiTi SMA wire

This research aims to model the shape memory effect (SME) of a shape memory alloy (SMA) wire in a commercial explicit finite element analysis (FEA) software, Ls-Dyna. A user defined material (UMAT) model was developed by implementing a one dimensional constitutive model into Ls-Dyna. A simple struct...
