Determining the Forming Limit Diagram by Experimental Methods

Abstract In general, a large part of the time is devoted to design and production reliable parts where extensive knowledge required for engineers come up with an optimal solution tooling sheet metal forming processes. Most time, principle trial error used get desired shapes products. This because prediction deformations occurring in elements not available highly dependent on geometry part, tools deformation process. Prediction limited by proper location necking, shear breakage, puckering material. Searching robust process expensive inefficient. The use numerical simulations provides alternative efficiency developing tool produce quality more efficient lower cost. Computer simulation extension theoretical science that based mathematical models. Such models attempt characterize physical or consequences scientific theories. purpose this work present way determining limit diagram various experimental methods.
