Abstract

THE CURRENT PAPER AIMED TO MODEL FAILURES AND FRACTURES IN SINGLE-LAP BOLTED JOINTS OF WOVEN FABRIC KENAF FIBER REINFORCED POLYMER (KFRP) COMPOSITE PLATE TO FAIL IN NET-TENSION. THE APPROACH WAS BASED ON THE ASSUMPTIONS THAT MICRO-DAMAGE EVENTS WERE DENSELY CONCENTRATED AHEAD OF THE NOTCH TIP AND CRACK GROWTH WERE READILY SEEN ALONG NET-TENSION PLANE IN A SELF-SIMILAR FASHION. A 3-D FINITE ELEMENT MODELLING FRAMEWORK WERE DEVELOPED TO EXPLICITLY INCORPORATE BOLT CLAMP-UP IN A RANGE OF KFRP SERIES FOLLOWING TESTED EXPERIMENTAL DATASETS. LAY-UP TYPES, NORMALIZED W/D, TEMPERATURE EXPOSURE WITH CONSTANT BOLT TORQUE OF 5 NM WERE CONSIDERED. IT WAS FOUND THAT KFRP PLATES UNDER ELEVATED TEMPERATURE WERE STRONGER THAN UNDER ROOM TEMPERATURE DUE TO MATRIX TOUGHENING. AN EXTENDED FINITE ELEMENT METHOD (XFEM) TECHNIQUE WAS USED TO MODEL DAMAGE GROWTH BY INCORPORATING CONSTITUTIVE MODEL OF TRACTION-SEPARATION RELATIONSHIP BASED ON INDEPENDENT EXPERIMENTAL MEASUREMENTS OF UN-NOTCHED PLATE STRENGTH, ΣO AND FRACTURE TOUGHNESS, GC OF ALL LAY-UPS UNDER INVESTIGATION. GOOD AGREEMENT BETWEEN THE PREDICTED AND MEASURED BEARING STRESS AT FAILURE WAS FOUND WHICH FAILED IN THE NET-TENSION MODE.
