| Abstract Scope |
Knowing a material’s fracture toughness is the first step towards preventing or delaying or at least predicting failure of a component. Over the past two decades, various size effects have been documented by several groups, which show ‘materials not really behaving themselves’ with respect to their mechanical response to applied loads. This naturally implies that the fracture toughness of their bulk counterparts cannot be exploited directly. Our group has been working on development of the clamped beam and clamped wire bending as a fracture test geometry that works for both macro and micro-length scales. Two such examples of its applications for multilayered and architectured structures will be shown. Analytical solutions of stress intensity factor or energy release rate will be provided where applicable. The use of clamped beam in R-curve determination and in interface fracture energy measurement will also be elaborated upon. |
