![عکس صفحه اول مقاله: Strength prediction in CFRP woven laminate bolted double-lap joints under quasi-static loading using XFEM Strength prediction in CFRP woven laminate bolted double-lap joints under quasi-static loading using XFEM](/preview/png/1466076.png)
The current paper is concerned with modelling damage and fracture in woven fabric composite double-lap bolted joints that fail by net-tension. A 3-D finite element model is used, which incorporates bolt clamp-up, to model a range of CFRP bolted joints, which were also tested experimentally. The effects of laminate lay-up, joint geometry, hole size and bolt clamp-up torque were considered. An Extended Finite Element (XFEM) approach is used to simulate damage growth, with traction–separation parameters that are based on previously reported, independent experimental measurements for the strength and toughness of the woven fabric materials under investigation. Good agreement between the predicted and measured bearing stress at failure was obtained.
