Greetings! I'm trying to do FE modeling of the copped reinforced by Cu3Ti3O nano-precipitates, in particular, I want to model the fracture of the precipitates and matrix under the tensile loading. However, little is known about the Cu3Ti3O phase, and no fracture mechanics-related data is available (i.e. critical stress, stress triaxiality, etc). The elastic moduli are available (Young, shear, bulk). Can I model the fracture using those?
