Research on the Stress Intensity Factor of the Crack Normal to and Dwelling on the Interface of the Cermet Cladding Part

Basing on the theoretical study on the stress intensity factor (SIF) of the crack normal to and dwelling on the interface of the cermet cladding part, the finite element analysis (FEA) of the crack SIF is made. The change laws of the SIF with the load action angle, the load Q, the clad thickness ratio h1/h and the elastic modulus ratio E1/E2 are obtained. The research results have theoretical and steering significance on the wide application of the cermet cladding part.
