In this study, the effect of stacking sequences on failure behavior of pinned composite plates was investigated. The laminated composite plates were made from epoxy matrix and glass fibers as reinforcement material. To observe the influences of joint geometry and stacking sequence on the failure mechanism, failure analysis were carried out experimentally. The nine different laminated composite plates were tested. The edge distance-to-hole diameter ratio (E/D) of specimens was designed from 1 to 6. Besides, the specimen width-to-hole diameter ratio (W/D) was only considered as 6. Experimental results point out that failure behavior is strictly influenced from both stacking sequences and geometrical parameters of composite specimens.
