Anisotropic polycrystals in which the shear tractions vanish at several locations of the grain boundaries are considered. For three-dimensional polycrystals whose crystals belong to the tetragonal, hexagonal or trigonal class, it is shown that the effective thermal expansion tensor is given in terms

We analyze the macroscopic deformation of a polycrystalline solid due to local deformation events in the core of grain boundaries. The central result is an equation that decomposes the effective macroscopic strain into contributions from three deformation modes, namely: (i) the elastic strain in the
