  • Boundary element analysis of cracked panels with Mechanically Fastened Repair patches
    The Journal of Strain Analysis for Engineering Design, 2002
    Co-Authors: Pihua Wen, M.h. Aliabadi, A Young
    Abstract:

    In this paper, lap joints and Mechanically attached Repairs containing cracks are analysed by the boundary element method. A coupled boundary integral formulation of shear deformable plate and two-dimensional plane stress elasticity is utilized to allow the modelling of bending and membrane forces. Stress intensity factors, three for the bending problem and two for the membrane problem, are evaluated from crack-opening displacements. Several examples are presented to demonstrate the accuracy and robustness of the proposed method. The stress intensity factor solutions are shown to be dominated by the bending effect.

  • Stress Analysis of a Stepped-Lap Bonded Repair Joint in Composite Laminate under Compressive Loading
    2013
    Co-Authors: Asha Kumari, Byji Varughese, D Saji
    Abstract:

    With increasing the usage of advanced composite materials in aircraft structures, it is required to have a suitable Repair technology for composite airframe. One of the primary requisites of the Repair in such structures is that the Repaired surface should not affect the aerodynamic contour. Adhesively bonded Repair joints are generally preferred over Mechanically Fastened Repair joints to avoid the stress concentration and achieve smooth aerodynamic surface. Significant numbers of research works have been carried on interface stress distributions for lap, butt and scarf adhesive Repaired joints under the static tensile loading. However, the behavior of stepped-lap adhesive joints under compressive loading has not been fully understood and there are not many literatures available on this subject. The present work focuses on stress analysis of a laminate that is Repaired through a stepped-lap joint Repair scheme. The stress analysis has been carried out and stress distributions in the laminate, patch and adhesive were studied. In order to establish and validate the FE approach for analysis of stepped-lap Repair joint subjected to compression, an experimental study also has been carried out. The strains from the analysis have been compared with the strains obtained from the test at important locations. Both the results have shown good agreement.
