    Z-pin through-thickness reinforcement is used to improve the impact resistance of composite structures; however, the effect of loading rate on Z-pin behaviour is not well understood. The dynamic response of Z-pins in mode ...
  • Mohamed, Galal; Allegri, Giuliano; Yasaee, Mehdi; Hallett, Stephen R. (Elsevier, 2017-03-26)
    Z-pins are an effective method of reinforcing laminated composite materials for resisting the propagation of delamination. In this paper, a novel numerical method combines the classical cohesive finite element (FE) method ...

    A numerical simulation is presented in this paper on the performance of crack retarders bonded to integral metallic structures. The work is described in two main parts. First, a novel modeling approach employing the ...

    Delamination resistance of composite laminates can be improved with through-thickness reinforcement such as Z-pinning. This paper characterises the bridging response of individual carbon fibre/BMI Z-pins in mixed mode ...
  • Yuan, Jie; Scarpa, Fabrizio; Allegri, Giuliano; Titurus, Branislav; Patsias, Sophoclis; Rajasekaran, Ramesh (Elsevier, 2016-11-06)
    This paper describes a review of the relevant literature about mistuning problems in bladed disc systems, and their implications for the uncertainty propagation associated to the dynamics of aeroengine systems. An emphasis ...
  • Zhang, Xiang; Boscolo, M.; Figueroa-Gordon, Douglas J.; Allegri, Giuliano; Irving, Phil E. (Elsevier Science B.V., Amsterdam., 2009-01-01)
    This paper presents an investigation on the effectiveness of crack growth retarders bonded to integral metallic structures. The study was performed by both numerical modelling and experimental tests. It focuses on aluminium ...
  • Allegri, Giuliano; Zhang, Xiang (Elsevier Science B.V., Amsterdam., 2007-04-01)
    The main objective of this paper is to investigate the benefits of Z-fibre pinning to improve the bonding strength of composite joints. The problem is addressed from a design point of view in order to develop a ...
  • Allegri, Giuliano; Zhang, Xiang (Elsevier Science B.V., Amsterdam., 2008-06-01)
    This paper addresses the usage of inverse power laws in accelerated fatigue testing under wide-band Gaussian random loading. The aim is not at predicting an absolute value of fatigue life but assessing the fatigue damage ...
