Abstract This paper presents a theoretical analysis of the dynamic large deformation response of highly circular arches under impact. By the Instantaneous Configuration Method (ICM), the solutions of the entire large deformation response process of the problem are obtained. The influences of the mass ratio, the energy ratio and the supported condition on the final deformation, the response time and the occurrence of plastic deformation are discussed in detail. The necessary condition for occurrence of the ‘local reverse bending’ phenomenon has been found. An approximate method is provided to describe the phenomenon. The numerical results are in good agreement with experimental data.
