Abstract: Fluid-structure interaction (FSI) is an independent branch of mechanics which comprises of fluid mechanics and solid mechanics. The crux of the FSI problem is the interaction between the flow field and solid deformation field. When the field is overlapping and penetrative, the coupling can be realized by establishing the differential equations of constitutive equations which are different from the single-phase medium. However, when the field is contrary to the above one, the coupling takes effect by the interface force. In this paper, the current research status of fluid-solid coupling numerical simulation methods is discussed from the point of view of continuum mechanics and non-continuum mechanics, and the shortcomings of the numerical simulation methods of fluid-solid coupling are described. The result of this research has instructive significance relevant for the development of FSI numerical simulation methods and helps engineers make better choices for reliable simulation methods for the physical behaviour of materials
