J. Weiss et al., THE NUCLEATION OF MICROCRACKS IN ICE CUBES COMPRESSED EQUALLY ON ALL BOUNDARIES, Philosophical magazine. A. Physics of condensed matter. Structure, defects and mechanical properties, 73(5), 1996, pp. 1385-1400
Calculations suggest that intergranular microcracks nucleated in ice c
ubes compressed equally on all boundaries (J. Weiss and E. M. Schulson
, 1995, Acta metall. mater., 43, 2303) are formed as the result of loc
alized deformation via grain boundary sliding activated by shear stres
ses which originate from the elastic anisotropy of the material.
