A two-dimensional sheet material is provided that is suitable for bending along a bend line to form a three-dimensional object. The sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one side of the bend line. A portion of the displacements shear adjacent the bend line and define an edge and an opposed face. The edge and opposed face configured to produce edge-to-face engagement of the sheet material during bending. Alternatively, sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one or both sides of the bend line, and with a plurality of corresponding and cooperating protrusions to improve structural integrity and/or to improve electromagnetic and radio frequency shielding. The sheet material may also be provided with a self-latching structure. A method of preparing and using these sheet materials is also described.
