Procedure to plot complete diagrams for deformation of sheet materials

As applied to ductile sheet materials a universal procedure is developed to construct complete strain diagrams according to the data of tests of a special flat specimen on machines of any pliability. General relationships for selection of geometrical dimensions of the specimen elements are substantiated. They provide construction of complete strain diagrams for a wide class of structural sheets. Experimentally obtained descendent sections of complete strain diagrams for 1Kh18N10T and St.3 (1 and 2 mm thick) steels are analyzed
