Once locked in position at a set reduction the wedged shape die is moved down over the surface of the strip which is therefore elongated and moves relatives to the fixed drawbar. Theironing device was equipped with a numberofload

The lap-shear test is illustrated in Fig. 3.13. It was originally made from two pieces of 1.6 mm metal strip one inch in width, bonded together over a length of half an inch. These dimensions have now (in Europe) been replaced by the metric equivalents shown in the figure. This testpiece is loaded to failure in a normal tensile testing

encouraged to compare the deformation modes described here and in the preceding chapter. Definition In sheet metal forming practice, we distinguish five basic modes of deformation: • STRETCHING: The material is expanded in both directions. This mode of deformation is found mostly on smooth bottoms of shallow parts and in hydroforming
