Patent number: 10633116Abstract: A method for joining two aircraft structural parts by a bolted or riveted joint and for preventing cracks at said joint includes providing a first metallic aircraft structural part and a second aircraft structural part, wherein the first aircraft structural part includes a first joint region and a second aircraft structural part includes a second joint region. Furthermore, the method includes inducing compressive residual stresses in a first area of the first joint region for preventing cracks by applying parallel crack retarding regions formed as stripes in the first area, drilling fastener holes in the first and second areas of the first. Finally, the method includes a step of fastening together the first and second aircraft structural parts at the first and second joint regions by a bolted or riveted joint.Type: GrantFiled: August 28, 2015Date of Patent: April 28, 2020Assignee: Airbus Operations GmbHInventors: Domenico Furfari, Nikolaus Ohrloff

Patent number: 10035577Abstract: A vehicle structure component reinforced by means of an area, a vehicle including such a vehicle structure component, and a corresponding method to reinforce a vehicle structure component are proposed. The area includes a compressive residual stress in a first direction and a compressive or tensile residual stress in a second direction being vertically aligned to the first direction, wherein the ratio of the compressive stress in the first direction and the compressive or tensile residual stress lies between ?0.2 and +1.0. Hence, the propagation direction of cracks in such areas is diverted, faster pressure equalization takes place, and further crack propagation is inhibited.Type: GrantFiled: November 13, 2013Date of Patent: July 31, 2018Assignees: Airbus Operations GmbH, EADS Deutschland GmbHInventors: Domenico Furfari, Elke Hombergsmeier
