Clearly, the delamination is a classic planar interfacial fracture under a mixed mode loading. Such a problem is very well studied in literature, even for non-linear cases [10]–[12]. The propagation of a crack at an interface is a function of interfacial fracture toughness, KIC, which depends upon Dundurs’ parameter for the system[11],[12].An obvious way to improve the toughness of this interface is to either roughen it (mechanical interlocking) and/or clean it to remove impurities and enhance the chemical bond.This needs to be completed without harming the ceramic EAC. The most effective method depends upon the interfacial chemistry, the material properties, and the crack geometry.
