Abstract
AbstractSpherical microindentation into the (100) surface of a fcc single crystal results in a remaining indent shape which looks rather like a square than like a circle. This contribution aims to elucidate this curious phenomenon observed in a recently performed experiment within SFB 298 at TU Darmstadt. The applied methodology is threefold: (i) On the modelling side, a phenomenological orthotropic finite‐strain plasticity model is proposed and applied within finite‐element simulations. (ii) On the experimental side, the topography of the indentation crater is reconstructed by means of scanning‐electron microscopy along with image‐processing. (iii) Experimental observations are explained by plastic slip mechanisms. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
