Failure Load Prediction of Bolted Single-Lap Composite Joint Based on XFEM

Abstract:

Composite materials have excellent mechanical properties and can be mechanically tailor designed, so the composite materials are widely used in civil engineering and structural system such as aerospace and shipbuilding industry. Numerous studies show that the damage of joints is main reason which results in composite structure failure. In this paper, extended finite element method (XFEM) is applied to investigate the failure load prediction of bolted single-lap composite joint. The influences of geometric parameter: edge-to-diameter (E/D) on failure load is investigated.
