The stress field of a dislocation array in an ultra thin anisotropic heterogeneous bicrystal

The problem of a dislocation parallel and close to two free surfaces of a thin foil made up of two plates of different nature, using anisotropic elasticity, is treated numerically. Different applications are presented for the thin homogeneous crystals Al/Al and Cu/Cu and also for the thin bicrystal...

Zusammenfassung:	The problem of a dislocation parallel and close to two free surfaces of a thin foil made up of two plates of different nature, using anisotropic elasticity, is treated numerically. Different applications are presented for the thin homogeneous crystals Al/Al and Cu/Cu and also for the thin bicrystal Al/Cu. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
