Metal sheet drawing - Mechanical aspects

Metal sheet drawing allows for the production of complex non extractable forms. The choice of the metal sheet must be adapted to the type of forming. Sound knowledge and description of the forces involved during the drawing process is thus essential. This approach allows for determining precisely the impacting role of mechanical characteristics such as the anisotropy coefficient, work-hardening coefficient, yield strength, tensile strength and elongation. Metallurgic aspects such as crystallography, grain size, surface and homogeneity of material must not be left aside as they also influence the suitability for forming.
