The results of the finite element analysis indicated that the\r\nexpansion ratio of the tube was mainly affected by the radius of the\r\npunch. However, the rupture was more affected by the punch angle\r\nthan the radius of the punch. The existence of a specific punch angle,\r\nat which rupture did not occur, even if the radius of the punch was\r\nincreased, was found.","references":"[1] M. Shakeri, S. Salehghaffari, R.
