Dvnarnic Reswnse of Laminated Com~osite Shell under Low-Velocity Impact
복합적층쉘의 저속충격에 대한 동적 거동 해석
Abstract
The dynamic behavior of graphite/epoxy laminated composite shell structure due to low-velocity impact is investigated using the finite element method. In this analysis, the Newmark's constant-acceleration time integration algorithm is used. The impact response such as contact force, central deflection and dynamic strain history form shell structure analysis are compared with those form the plate non-linear analysis. The effects of curvature, impact velocity and mass of impactor on the composite shell are discussed.
