Description

The performance of intelligent devices with engineering responses dependent on nonlinear coupling of heat, magnetism, electricity and elasticity (TMEE) is of increasing interest due to their superb engineering properties and performance. These devices which are composed of smart TMEE structures could have their engineering properties tailored-made to suit the design requirements. Understanding the engineering behaviours of these structures is pertinent to minimizing catastrophic failures and optimizing structural design capabilities for enhanced performance.In this proposal, a new symplecticity approach will be developed to analyze the static and dynamic responses of TEMM structures with multi-field coupling. It is based on the Hamiltonian variational principle with Legendre transformation. Some preliminary breakthroughs to the long-standing bottleneck-problems have been reported and more comprehensive breakthrough is expected. Based on the exact solutions derived, the outcomes will play substantial roles to the completeness and more thorough understanding of the engineering behaviour of these coupled systems.
