Each layer of laminated connector material has different material properties, so the reaction forces between them are uncertain. This paper presents a simplified equivalent single composite material model for simulating the laminated connector materials. Finite element simulation results are then compared with experimental data. Small differences between the numerical results and Hopkinson-bar experimental results verify the accuracy of this finite element model. Numerical simulations of a cylindrical shell structure under impulsive loadings are then conducted using the finite element analysis software ANSYS/LS-DYNA. The results show that the equivalent single composite material model is valid and accurate. Source
