Abstract: Objective of this paper is study the bearing strength and failure modes of the Fiber Metal Laminates prepared by hand layup technique in two different stacking sequences. Parameters like ratio of hole distance to hole diameter (e/D), ratio to the width of composite to hole diameter (W/D) are varied during the experiment. Hole diameter is kept constant as 6mm and e value is taken as 6mm, 12mm, 18mm, 24mm, 30mm and 36mm. Similarly the width of the FML specimen is maintained as 24mm and 36mm respectively. Results show that laminate with [Ca0°/Ca90°/Al/Ca90°/Ca0°]s orientation is having a bearing strength 3.94% higher than that of [Al/Ca0°/Ca90°/Al/Ca0°]s orientation. In terms of failure modes the specimens with distance-diameter ratio greater than 3 and the two width- diameter ratio 4 and 6 exhibited bearing failure. For smaller ratios, the failure is due to shear out which involves combination of bearing and net tension failure.
