A New Computational Methodology for Structural Dynamics Problems

Abstract

Most structural components encountered in army vehicles and armor can be classified as beams, plates, or shells for analysis purposes. While these structural elements are designed to function properly under thermo-mechanical loads encountered in their use, they do develop high stresses and experience high vibration frequencies that may make them non-functional in actual service conditions. The objective of this research is to develop consistent plate and shell theories and associated computational framework for linear and non-linear problems of structural dynamics: (1) develop accurate and consistent structural theories and associated finite element models of plates and shells that account for transverse shear deformation and illustrate the accuracy using benchmark plate and shell problems. (2) Develop mixed and least-squares finite element models of the refined theories for the analysis of plates and shells.
