Three-Dimensional Strain Analysis of Single-Lap Bolted Joints in Thick Composites Using Fibre-Optic Gauges and the Finite-Element Method

摘要: Bolted joints involving composite plates used to be almost entirely dedicated aerospace applications. As the need for energy conservation has increased, field of bolted found new applications in ground armoured vehicles. Thick panels able withstand large in-plane and impact loads are critical. The present investigation evaluates interior strain field, through thickness, a plate connected an aluminium panel with single-lap joint. area interest is bearing plane region close hole because presence stress concentrations that heavily modify field. Experimental data joint were recorded by fibre-optic gauges embedded plate. Numerical analyses performed using ANSYS as pre-processor LS-DYNA solver. overall goal was evaluate magnitude contact strains around thickness composite. These v...
