Abstract:

This paper summarizes basic research (i.e., testing and analysis) ; conducted to examine the deformation behavior of flat-welded ; steel sandwich panels under two types of quasi-static loading: ; (1) uniaxial compression; and (2) bending through an indenter. ; The objectives of these tests were to: (1) confirm the analytical ; and computational (i.e., finite element) modeling of sandwich ; structures, (2) examine the fabrication issues associated with ; such structures (e.g., material selection and welding processes), ; and (3) observe the deformation behavior and local collapse ; mechanisms under the two different types of loading. In ; addition, the uniaxial compression tests were performed to rank ; or screen different core geometries. Five core geometries were ; examined in the compression tests: pipe or tubular cores with ; outer diameters equal to 2, 3, and 5 inches; a 2-inch square ; diamond core; and a double-corrugated core called an X-core ; with a 5-inch core height.
