Abstract

Abstract: In order to find the deformation behavior and boundary effect of fiber-metal laminate (FML) under uniaxial tensile loading， mechanical tests were carried out on GLARE2-3/2， GLARE3-3/2 and GLARE6-3/2 laminates. A new method of digital image correlation was introduced to record the surface strain of the GLARE laminate samples during loading. The stress-strain curves， strain cloud chart and strain-loading time curves show that the deformation of GLARE2-3/2 laminates is uniform，without obvious boundary effects; the GLARE3-3/2 laminates have instantaneous performance degradation and boundary effect， and the GLARE6-3/2 laminates have two performance degradation and the boundary effect is opposite to that of GLARE3-3/2 laminates.

Key words: fiber-metal laminates, stress-strain curve； failure mechanism； non-linear behavior； glass fiber； epoxy resin
