Interface effect of nanoscaled adhesive interlayer on force transfer in biological microjoint

Abstract

The interface effect of nanoscale adhesive interlayer plays a significant role in force transfer in biological microjoint. In this letter, the authors adopted shear lag theory and Gurtin–Murdoch model to investigate the influence of two typical residual interface shears on stress distribution. The dominant governing equations of global interfacial shear stress are established using the stress jump across the interface and the continuity condition of interlayers. The transferred force is evidently reduced by the parabolic residual interface shear, and linear residual interface shear exerts no influence on the axial force of hard layer. This study might be helpful for the parametric investigation on stress transfer in a complicated microjoint and the interface design of nanocomposite.
