Abstract
Newly developed experimental methods allow the extension of surface strain measurements into
three dimensions throughout the bulk of opaque materials. By comparing two specimens with different geometries but consisting of similar materials under compression deformation, the ability of one of these new methods to distinguish between homogeneous and heterogeneous response to identical macroscopic boundary conditions is illustrated. Extending a previous study of a specimen deforming homogeneously to the entire specimen volume rather than a small
subvolume, the effect of the marker particles on the material properties is discussed.
