| Abstract: | This paper presents a large deformation mode of a sem- icircular arch, which is struck by a dropping hammer on its top. The dynamic response of the rigid-viscoplastic arches is evaluated based on the Cowper-Symonds constitutive relation, and the strain hardening effects have been taken into consideration in the numerical calculation. |
