N2 - Missile impact against a continuously supported rigid-plastic beam results in only a transient phase of deformation that continuously evolves towards the primary dynamic mode; ther is no modal phase of deformation. Large deflection effects are incorporated in this analysis by considering interactions between plastic bending and stretching in deforming regions. Normal resultant forces associated with stretching are shown to be most important when the impact point deflection exceeds the beam thickness; in comparison with a small deflection solution, these forces substantially decrease the final deformation.
