Nonlinear Static and Dynamic Analyses of a Generic Enclosure Subjected to an Internal Pressure,

Abstract

Nonlinear elasto-plastic static and equivalent dynamic analyses of a box shaped generic enclosure subjected to an internal quasi-steady residual overpressure have been conducted using the ADINA finite element analysis code. The results indicate substantial deflection of the sidewalls and stress concentration effects at the corner joints between walls of the generic enclosure. Peak static deflection in excess of twice the wall thickness was predicted at both 38 and 54 MPa overpressures which are in satisfactory agreement with large deflection theory of plates.
