摘要: In this study, a failure analysis of glass-epoxy laminated composite bolted-joints with bolt/hole clearance under various torques was carried out. To estimate the effects joint geometry and fiber orientation on strength mode, parametric studies were conducted experimentally. The two dif- ferent geometrical parameters edge distance-to-hole diameter ratio (E/D) plate width-to-hole (W/D), E/D selected from 1 to 5, W/D chosen 2 5. bolt preload torque also out as 0, 3, 6 Nm. investigate material effect, plates oriented three different stacking sequences (90 o )8, (45 (0 )8. experiments between diameters circular hole 5 mm, respectively. According experimental results, mode bearing are strongly influenced by both para- meters parameters. Additionally, when is applied bolted-joints, mechanism affected its increasing values.
