Finite Element Dynamic Analysis of the DCT-2 Model

Abstract

This report discusses quasi three-dimensional finite element dynamic analysis performed for a buried reinforced concrete cylindrical shell explosive test conducted by AFWL at Kirtland AFB, NM. The test (conducted on 27 Feb 81) included two horizontal ICBM shelter models with rectangular roof cut-outs, inner steel liners, longitudinal interior rails, and two different thickness to inner radius ratios (0.18 and 0.28). Both models were subjected to a combined axial and transverse simulated nuclear environment. The finite element analysis examines the axial response to include the initial compressive wave, structure- media interaction loads, longitudinal vertical bending, axial strains and motion, and effects of certain structural details such as rectangular roof cutouts and varying thickness to internal radius ratio. The reinforced concrete material model is piecewise linear, perfectly plastic with smeared steel.
