文摘
- •
A new 3D phenomenological model for SMAs is introduced accounting for reorientation.
- •
It is built to capture material behavior under complex non-proportional loading.
- •
Inelastic strain mechanisms are rigorously described in the meso- and macro-scale.
- •
The thermomechanical aspects of the coupled modelisation is fully investigated.
- •
Existing experiments of complex loading paths have been numerically simulated.
