Abstract

In this paper, at the first time, dynamic response of double curved, single curved, flat and circular cylindrical composite shells with simply supported and clamped boundary conditions subjected to multi- mass impacts were studied based on the first-order shear deformation theory (FSDT). The mechanical strains were used according to Sander’s theory. Using a NEW LINEARIZED two degrees of freedom spring-mass system (linear form of HERTZIAN contact law) and complete solution model (nonlinear form of HERTZIAN contact law), the results are derived and compared with together. For additional verification, the results are compaired with the Abaqus finite element software and the latest available literature. The presented formulation is general and capable to analyses the cylindrical composite shells subjected to multi-mass impacts with arbitrary different masses, initial velocities and impact locations. In this investigation, the effect of geometrical and mechanical parameters, such as length to width ratio (a/b), length to radius ratio (L/R) and velocity of the impactor masses on the impacts response from both presented models are studied and compared with together.
