Scattering of oblique flexural waves by a through crack in a conducting Mindlin plate in a uniform magnetic field

Considering a shell as a genuine Cosserat surface leads naturally to a definition of material uniformity which entails an enlarged isotropy group operation. A strict homogeneity condition is obtained in terms of the vanishing of a surface inhomogeneity tensor and two director integrability conditions. © 1998 Elsevier Science Ltd
