Directional dependence of the Young modulus Y of (a) Si, (b) Cu, and (c) W. The left panel gives 3d-polar plots of Y, the right panel shows the azimuthal variation of Y within the (111) plane. Y is given in parentheses for the [001], [111], and [110] direction. Note the almost isotropic behavior for W.
