The first connecting strut column couples the first expansion column to the second expansion column. At least a portion of the plurality of the first serial connecting struts have a first stair-step and a second stair-step. The first expansion column, second expansion column, and first connecting strut column form a plurality of geometric cells. At least a portion of the plurality of geometric cells are asymmetrical geometric cells.
