Saturation impulses for dynamically loaded structures with finite-deflections
Zhao YP, Yu TX, Fang J

 
Abstract
    The concept of \'\'Saturation Impulse\'\' for rigid, perfectly plastic structures with finite-deflections subjected to dynamic loading was put forward by Zhao, Yu and Fang (1994a). This paper extends the concept of Saturation Impulse to the analysis of structures such as simply supported circular plates, simply supported and fully clamped square plates, and cylindrical shells subjected to rectangular pressure pulses in the medium load range. Both upper and lower bounds of nondimensional saturation impulses are presented.

 
Key Words
    structures, rigid, perfectly plastic, finite-deflections, rectangular pressure pulse, saturation impulse, lower bounds, upper bounds
