In the present work the effect of the nanoclay on the bearing strength and failure mode of the pin joints was investigated both experimentally and numerically. Geometric parameters, i.e. the distance from the free edge of specimen to the diameter of the first hole (E/D) ratio and width of the specimen to the diameter of the holes (W/D) ratio were investigated. The E/D and W/D ratios were varied from 1 to 5. Tsai–Wu failure criterion with characteristic curve method and progressive damage analysis was used for the prediction of failure modes. Results showed that bearing strength and failure mode were considerable affected by the wt% of nanoclay and the geometric parameters. A good agreement was obtained between experimental and numerical predictions.
