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.
