Abstract
The dynamic responses of composite laminated plates and shells due to inelastic impact are analyzed by using the finite element method. In the inelastic impact analysis, the structure is considered to be elastic, but the loading is idealized as inelastic. A modified isoparametric linear shell element, in which the shear deformation and rotatory inertia are taken into account, together with the theory of conservation of momentum and Newmark time integration method are used to solve the set of finite element equations. The influences of shell curvature on the impact response are investigated and discussed. The impact experiments are performed and the experimental results are in good agreement with the finite element solutions.
