An interface stress model for strength analysis of CFRP/Al (carbon fiber reinforced plastic/aluminum) composite component

The introduction of the full paper reviews Refs. 1 through 12 and then proposes our interface stress model, which is explained in section 1. Its core is that we derive eqs. (28) and (29) by using composite laminated plate theory, equilibrium equations and equations of bonded joints, all of which consider the bending moment caused by eccentricity of single-lap bonded joints. In section 2, we use Figs. 6, 7 and 8 to compare the solution of our theoretical interface stress model with the calculation results of three-dimensional finite element analysis; the comparison shows preliminarily that our interface stress model is usable.
