  • Method of manufacturing an elongate component
    Patent number: 9201417
    Abstract: A method of manufacturing an elongate element (10) using a punching operation assumes a polynomial relationship between punch depth (dpunch) and neutral axis, with the constants being a polynomial function of plastic deformation of the beam. Using finite element analysis, a relationship between the required plastic deformation, the second moment of area of the element and the neutral axis of the element can be derived.
