Abstract
ABSTRACTThe present paper aims to predict the bearing stress at failures of woven fabric kenaf fibre reinforced polymer with single-lap hybrid joints under quasi-static testing. Testing series investigated includes a variation of joint types, normalised W/d, lay-up types, plate thickness and bolt loads. Initially, cohesive failures appeared within adhesive layer, followed by net-tension failure mode in all testing series investigated associated with stress concentration. Strength prediction was carried out subsequently by implementing XFEM framework with an embedded traction-separation relationship within ABAQUS CAE. The experimental datasets and XFEM results were evaluated where good agreements were found in the combination of cross ply and thicker coupon with a discrepancy of less than 5%.
