A process for designing and manufacturing precision-folded, high strength, fatigue-resistant structures and a sheet therefore. The techniques include methods for precision bending of a sheet of material (41, 241, 341, 441, 541 ) along a bend line (45, 245, 345, 445, 543) and a sheet of material formed wi th bending strap-defining structures, such as slits or grooves (43, 243, 343, 443, 542), are disclosed. Methods include steps of designing and then separately forming longitudinally extending slits or grooves (43, 243, 343, 443, 542) through the sheet of material in axially spaced relation to produc e precise bending of the sheet (41, 241, 341, 441, 541) when bent along the be nd line (45, 245, 345, 445, 543). |
