Abstract
A new adaptable grid or lattice structure identified by the coined term “polargrid” is disclosed. A polargrid may be designed or engineered to fill any space between two generally circular structures and where the ribs will intersect with both circular structures at a node. The intersection of a polargrid with a circular structure will not occur mid-rib. Rather, a polargrid can be designed to always have ribs terminate at an inner or outer circular structure at a node. Polargrids have particular applicability in cylindrical structures or when interconnecting concentric circular or cylindrical structures that may or may not be co-planar.
