This chapter describes the fundamentals of structural impact mechanics. It explains the theories and methodologies that can be commonly applied to both steel‐ and aluminum‐plated structures. Structures can be subjected to dynamic or impact loads during service. Three types of dynamic or impact loadings are normally considered: impact, dynamic pressure, and impulsive loading. The load effects of structures under static or quasistatic loading are normally calculated via the classical theory of structural mechanics or linear elastic finite element analysis. The stresses in structural materials under a given magnitude of impact loading in the elastic‐plastic regime increase as the strain rate increases. The chapter shows the ultimate strength behavior of the plate under impact axial compressive load, varying the loading speed in a certain range. N. Jones proposes the rigid‐plastic approach to compute the permanent deflection of beams and rectangular plates loaded by a pressure pulse, taking into account the large‐deflection effect.
