Abstract
Elastic–plastic finite element analyses have been performed to study the compressive stress effect on fatigue crack growth of the glass fiber reinforced aluminum alloy laminates (GLARE) under applied tension–compression loading. The crack opening displacement and plastic zone size were obtained for the aluminum layer in GLARE. The differences of parameters near the crack tip under tension-compression and tension-tension loading were observed. The results have shown that the displacement and reverse plastic zone size continue to change with the applied compressive stress. Based on the finite element analysis results, a fatigue crack propagation model of GLARE has been proposed.
