... affected the interfacial shear strength significantly. According to the calculated Tabor parameter, the JKR model was selected to approxi- mately calculate the contact area and the interfacial shear strength. ... substrate modified the true contact area, which affected the interfacial shear strength. Continuum mechanics calculation found that interfacial shear streng...
