A thin, stressed, solid cylinder, a whisker, is subject to mass transport by curvatureand elastic-stress-driven surface diffusion. The stability of the cylindrical surface is examined using linear stability theory. The presence of elastic strains can excite nonaxisymmetric modes, which, under certain conditions, are preferred and can give rise to helical surfaces.
