We present an experimental methodology for determination of all 21 elastic constants of materials with general (triclinic) anisotropy. This methodology is based on contactless resonant ultrasound spectroscopy complemented by pulse-echo measurements and enables full characterization of elastic anisotropy of such materials from measurements on a single small specimen of a parallelogram shape. The methodology is applied to two benchmark examples: a material with generally rotated cubic anisotropy (single crystal of silicon) and an isotropic material (silicon-infiltrated silicon carbide ceramics). In both the proposed approach is able to provide a full triclinic tensor with relatively low experimental errors and to identify indubitably the anisotropy class of the material; for the cubic material also the orientations of the principal axes and the cubic elastic coefficients are reliably determined.
