Abstract

The objective of the study is to investigate the effects of geometrical and physical parameters on failure loads unidirectional composite laminates by finite element analysis. The failure load of for a single pin hole, parallel pin hole and multi-pin holes. Three different distance variables were investigated during analysis the ratio of free edge distance to the outer holes/pin diameter (E/D = 2, 3, 4, 5), the ratio of longitudinal distance between the holes/pin diameter (G/D = 2, 3, 4, 5), and the ratio of transverse distance between the parallel holes/pin diameter (W/D = 2,3, 4, 5) ratios. Yamada-Sun failure criterion was used for failure analysis. The results from finite element analysis showed that it is very important to consider the effect of E/D, G/D and W/D ratios in design of single, double and multiple joints. The results showed that the pin hole farthest from the free edge is subjected to the highest stress.

Keywords- Composites, ANSYS Workbench, Pin Loaded joints, parallel pinned joints, multiple pin joints.
