Constitutive Modeling of multi-stimuli-responsive shape memory polymers with multi-functional capabilities

Nowadays, shape memory polymers (SMPs)-based devices are required to be much smarter produce large recovery and force with lower working temperatures in order enable multi-functionality them. They could play a vital role the advancement of multi-functional soft robot manipulators, biomedical tools wearable where is key challenge must around body temperature, or sustainable smart systems low energy consumption. The aim this paper introduce thermo-electro-magneto-responsive fibrous SMPs (TEMFSMPs) as new class highly enhanced reduced temperature. A three-dimensional constitutive model developed simulate thermo-electro-magneto-visco-hyperelastic behaviors under deformation for first time. Constitutive relations derived by adopting an electro-magneto-visco-hyperelasticity theory implementing it thermo-mechanical cycle SMPs. To improve strength SMPs, bunch fibers also embedded into SMP matrix. Then, proposed uniaxial tension complex loading regimes such simultaneous torsion extension solved semi-analytically. In addition, response through validated via available experimental tests. Numerical results reveal that electro-magnetic features can significantly enhance TEMFSMPs their temperatures.
