摘要: In this study, the effect of preload moments on failure response glass-epoxy laminated composite bolted-joints with bolt/hole clearance was investigated. To evaluate effects bolted-joint geometry and stacking sequence plates bearing strength mode, parametric analyses were performed, experimentally. Two different geometrical parameters, edge distance-to-hole diameter ratio (E/D) plate width-to-hole (W/D), examined. For reason, E/D selected from 1 to 5, whereas W/D chosen 2 5. Besides, applied as 0, 3 6 Nm. Due estimating material parameters effect, oriented three groups, [0°/0°/90°/90°]s, [45°/45°/—45°/—45°]s [60°/60°/—60°/—60°]s, symmetrically. The experiments also performed under a for diameters bolt circular hole 5 mm, respectively. Experimental results showed that mode bea...
