Consequently, the analytical solution of bending of elastic three-dimensional two-layer composite beams with interface compliance is derived for the first time. In the illustrative example, a three-dimensional two-layer cantilever composite beam made of 6061-T6 aluminum and C83400 red brass is analyzed. It is shown that interface compliance could have a significant influence on the mechanical behavior of such a structure. Finally, the results for different mechanical quantities are tabulated and as such the analytical solution presented can be used as a benchmark solution of three-dimensional bimetallic composite beams %K Composite %K layer %K interfacial slips %K analytical %K bimetallic %U https://journals.sagepub.com/doi/full/10.1177/1464420718803704
