The cut-and-try method of determining sheet metal formability has long been the standard practice in the aircraft industry. This two-volume report presents methods of determining formability analytically for the twelve most common processes of forming sheet metal. This method is based on utilization of a material's mechanical properties to predict formability. The first volume on development gives the procedure used to arrive at the objective of predicting formability. First, basic limit equations are developed relating geometry of the parts to the material properties. These equations are used to determine the shape of the limit graphs and to give indices relating formability to the material. Then, experimental parts are formed to position the theoretically shaped curves with the aid of the formability indices. The second volume on application is presented in handbook form giving design and manufacturing information for nineteen materials in the program. These materials covered some of the most currently used alloys: magnesium, aluminum, titanium, stainless steel, nickel and cobalt base and refractory metals.
