When laminae are smaller than the wavelengths that measure them, a composite appears homogeneous and anisotropic. Composites are often subjected to high temperature gradients during their fabrication which can result in residual stresses, and damage

Summary In a system of plane parallel fractures, it is often assumed that resistance to slip on the fractures is independent of the direction of that slip. The fracture system then is transversely isotropic in its elastic properties and can be charac

A heterogeneous mixture of isotropic elements may appear homogeneous and anisotropic when the scale of its fabric is smaller than the seismic wavelengths that measure it (Backus, 1962). These fabrics can result from thin layering or from oriented mic

A material may appear homogeneous and anisotropic when the scale of its fabric is smaller than the wavelengths that measure it. These structures can result from a variety of causes such as the thin layering in composites or stress resultant oriented

A finely layered medium or a system of parallel fractures in an otherwise homogeneous elastic background renders the medium anisotropic for long wavelengths. The anisotropy increases in complexity as the number of different systems incorporated into

A structure appears anisotropic when it consists of a fabric that is thinner than the seismic wavelengths that measure it. This fabric can result from periodic thin layering or microcrack orientation. The horizontal layering in sedimentary basins and
