Abstract : An analytical parametric study of low velocity impact on orthotropic plates and tubes is conducted. Relationships are established between the dynamic structural deflection and the impact parameters such as impactor mass, velocity, height of drop, energy level, etc. The severity of the loading on the structure is determined relative to the impact parameters and the natural frequency (first mode) of the structure.
