Abstract
In structures applications, composite components are joined by bolted connection is commonplace requires introduction of drilling multi-holes. In order to study the structures response of these material properly, a parametric study on stress analysis is required to take into account arrays of variation including lay-up types, multi-hole configurations, intensity of applied stress etc. The failure and fracture of composite plates is somewhat complex, stress analysis study from numerical modelling able to predict the location of crack exhibited. Current study implemented 2-D finite element analysis (FEA) modelling framework on various multi-holes configurations woven fabric kenaf composite (WFKC) plates, the findings are then compared with conducted experiment. It was found that in non-staggered holes, maximum stress occurred at the outer holes suggesting net-sectional failure to initiate and self-similar crack behaviour through plate thickness. On the contrary, net-sectional failure in staggered hole configurations are dependent upon smallest net-sectional area in any line perpendicular to plane axis. The stress analysis conducted provides good agreement with conducted experiment.
