SATURATION IMPULSES FOR DYNAMICALLY LOADED STRUCTURES WITH FINITE-DEFLECTIONS

The concept of ''Saturation Impulse'' for rigid, perfectly plastic str uctures with finite-deflections subjected to dynamic loading was put f orward by Zhao, Yu and Fang (1994a). This paper extends the concept of Saturation Impulse to the analysis of structures such as simply suppo rted circular plates, simply supported and fully clamped square plates , and cylindrical shells subjected to rectangular pressure pulses in t he medium load range. Both upper and lower bounds of nondimensional sa turation impulses are presented.
