Before revision: Faber model A mechanics of materials model, developed by Katherine Faber , has been developed to predict the increase in fracture toughness in ceramics due to crack deflection around second-phase particles that are prone to microcracking in a matrix.
After revision: Faber-Evans model The Faber-Evans model, developed by Katherine Faber and Anthony G. Evans, was developed to predict the increase in fracture toughness in ceramics due to crack deflection around second-phase particles that are prone to microcracking in a matrix.
