Evaluation of fracture toughness measurements using chevron-notched silicon and tungsten microcantilevers

Abstract:

Measuring the fracture behavior of small specimens of semibrittle materials such as tungsten is often difficult due to the lack of crack stability and a high ratio of the crack tip plastic zone size to specimen dimensions. To overcome this, microcantilever bending tests were used with a stable chevron notch geometry coupled with elastic–plastic fracture mechanical (EPFM) analysis. The chevron notch geometry was first validated by measurement of the (111) cleavage toughness in single-crysta...
