Study of Dynamic Response of Shell Structures to Blast Loads.

Abstract

This report presents an effort to model the response of cylindrical shells to fuel air explosions and mild high energy explosion. Two different methods were used in the analysis. The first method assumes small strain to derive the equation of motion using a force balance method. The second method was based on finite strain coupled with an energy method using a Lagrangian formulation for the equations of motion. Several equations of motion are derived for the finite strain case using several mode shapes for both full shell stiffness and half shell stiffness. Spatial integration was performed by hand and the resulting equations of motions were solved numerically using a CDC 3600 MIMIC Source Language Program. (Author)
