Fracture anisotropy in silicon single crystal

WebJun 24, 2005 · Results are presented for surface and mid-plane of the specimens. The results demonstrate that accounting for 3D elastic anisotropy is very important for accurate prediction of slip activation near fcc single-crystal notches loaded in tension. Results from the study will help establish guidelines for fatigue damage near single-crystal notches. WebJan 31, 2011 · The fracture toughness on the {110} fracture plane of single crystal silicon was determined to be 1.19 MPa m 1/2 for the {100} tensile surface and 1.05 MPa m 1/2 for the {110} tensile surface using the indentation-strength three-point bending method. The fracture surface features of these two orientations are correspondingly different.
