The generation of aerodynamic forces of oscillating bodies is the result of several physical phenomena interacting each other. The classification of Vortex-Induced Excitation (VIE) and Motion-Induced Excitation (MIE), together with their modeling, is only partially satisfactory mostly due to the mentioned interactions. In this paper, we describe the apparently simple case of a square prism oscillating within a smooth flow demonstrating the occurrence of VIE-MIE interactions and multiple lock-in conditions. The discussion is largely based on the distinction between synchronous and asynchronous force components and their separated analysis.
