PROBLEM TO BE SOLVED: To provide a method of preparing a sheet of material so as to bending along a bend line.SOLUTION: The method of preparing a sheet of material for bending along a bend line, includes the step of forming of at least one displacement in the thickness direction of the sheet of material with a portion of the periphery of the displacement closest to the bend line providing an edge and opposed face configured in position to produce edge-to-face engagement of the sheet on opposite sides of the periphery during bending. The forming step is preferably accomplished using one of a stamping process, a punching process, a roll-forming process and an embossing process. A sheet of material suitable for bending using the process also is disclosed, as are the use of coatings, shin guards and displacing the area of the sheet between bending inducing slits.

PROBLEM TO BE SOLVED: To provide an anisotropic reinforcing metal plate which ensures high rigidity and yield strength and has stable hysteresis characteristics by being reinforced with a metal plate receiving shearing force. SOLUTION: The anisotropic reinforcing metal plate comprises a rectangular metal plate receiving a shear load, a peripheral frame material arranged in a form of a picture frame on one surface or both surfaces of the metal plate, and a plurality of reinforcing members arranged on both surfaces or one surface of the metal plate so as to be parallel to one side of the peripheral frame and separated from each other. As the peripheral frame material and the reinforcing members still have an elastic cross section at shear yielding of the metal plate, the metal plate maintains shear yield strength and ensures stable hysteresis characteristics even after shear yielding.
