Abstract
The energy variation of a cylindrical whisker is calculated when sinus oidal fluctuations appear on its lateral surface. Calculation demonstr ates that, beyond a critical value sigma(0)(p), the applied stress all ows the surface to develop instabilities of short wavelengths. A kinet ic study of the surface evolution has been performed to characterize t he development of these instabilities when surface diffusion occurs.
