Abstract Personnel of the U.S. Army Engineer Research and Development Center (ERDC), Geotechnical and Structures Laboratory (GSL), Engineering Systems and Materials Division (ESMD), Concrete and Materials Branch (CMB), Vicksburg, Mississippi, were asked to examine the mechanical properties and microstructure characteristics of a commercially available steel cylindrical shell in its as- manufactured condition. To examine the mechanical properties, uniaxial tensile experiments were performed on ASTM dog-bone specimens and hoop cross-sectional specimens at displacement rates of 0.1 in./min., to obtain the stress-strain material responses. A commercially available image-analysis program determined the void volume fraction (VVF), the nearest neighbor distance (NND) of pores, maximum and minimum pore sizes, and aspect ratio of the pores at 30-degree increments of the steel hoop cross-sections. The results of the investigation allow for an improved understanding of the mechanical behavior of steel cylindrical shells.
