Abstract (VO)
Résumé

In this Note, we prove that the identity matrix is an inner point of the quasiconvex hull K^qc of a compact set $K \subset {X \in 𝕄^{3, 3} : \det X = 1}$ whenever K^qc contains a three-well configuration. This is in particular the case for the cubic to tetragonal and the cubic to orthorhombic phase transformations, and answers a question discussed in S. Müller, Microstructures, phase transitions and geometry, in: A. Balog et al. (Eds.), Proceedings European Congress of Mathematics, Progr. Math., Birkhäuser, 1998.

Dans cette Note, nous démontrons que la matrice identité est un point intérieur de l'envelope quasiconvexe K^qc d'un ensmble compact $K \subset {X \in 𝕄^{3, 3} : \det X = 1}$ lorsque K^qc contient une configuration de type triple puits. Ceci est le cas en particulier pour les transformations de phase de cubique à tétragonal et de cubique à orthorhombique, et répond à une question discutée dans S. Müller, Microstructures, phase transitions and geometry, in: A. Balog et al. (Eds.), Proceedings European Congress of Mathematics, Progr. Math., Birkhäuser, 1998.
