ABSTRACT
This chapter illustrates the concept and research method for saturated impulse whilst a square plate under rectangular pressure pulse is taken as a typical example. The saturated impulse of the fully clamped square plate under linearly decaying pressure pulse is presented to discuss the influence of impulse shape on the dynamic plastic response of plates. The existence of the saturated impulse for elastic-plastic plates was examined; a “saturated duration” for rectangular loading pulse was proposed; and a transverse displacement curve was provided based on the elastic-plastic numerical calculations. The chapter summarizes the research progress on saturated impulse for ship plates under dynamic loading, and promote the development of this issue consequently. There are two saturated impulses refer to saturated maximum deflection and saturated final deflection respectively. In addition, the elastic-plastic analysis also indicates that a certain amount of impulse is required to produce plastic deformation.
