Application of the Beam Theory to Model the Pseudoelastic and Ferroelastic Bending of SMA Beams

L. Orgeas
D. Favier

Résumé

The study of simple beams made of shape memory alloys (SMA) is very interesting for industrial and experimental reasons. In this paper, it is realised using strength of materials' approach : different kinematical and behavioural assumptions are successively used to solve circular and three supports bendings' problems. The kinematical ones consist in taking into account small or large displacements, the friction being or not neglected, whereas the behavioural ones consider different constitutive equations ie. the elastic-perfectly plastic model and the asymmetric elastohysteretic model. The influences of all these hypothesis are fïnally illustrated in three supports bending simulations.
