  • 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.
    Type: Grant

    Date of Patent: December 1, 2015
    Assignee: Airbus Operations Limited
    Inventors: Wei-Ming Sim, Oluwamayokun Adetoro, Pihua Wen
  • Method and apparatus for measuring residual stresses in a component
    Patent number: 8997577
    Abstract: A process for measuring the through stress distribution (12) in a workpiece (10) by taking progressive cuts (14, 16) and measuring the deflection of the workpiece at the cut point.

  • Method and system for making holes in composite materials
    Patent number: 8197162
    Abstract: A method of making a hole in a composite material comprising the steps of providing an elongate cutting tool having a cutting portion in the form of a tubular cylinder; and advancing the cutting tool in a direction parallel to a longitudinal axis of the cutting tool whilst rotating the cutting tool about said axis and vibrating the cutting tool along said axis.
