When a solid is submitted to constant and homogeneous applied stresses, sinusoidal instabilities are supposed to develop by diffusion on its surface. When sources of non-homogeneous stresses like defects are present in its bulk, localized instabilities seem to be more adapted to describe its surface evolution.
