Abstract
Off-axis tensile behavior of two grades of hybrid laminates, GLARE-2 and GLARE-3, made of unidirectional glass/epoxy laminae (GFRP) and aluminum (Al) alloy sheets is examined for various fiber orientations, and the differences in mechanical properties between the unidirectional and cross-ply hybrid laminates are quantified. The problem of accurately describing the nonlinear deformation of GLARE laminates under off-axis loading conditions is revisited, and the effect of local nonlinear deformation in the constituent GFRP layers on the overall inelastic behavior of GLARE laminates subjected to inclined tensile loading is elucidated by means of elastic-plastic finite element (FE) analyses.
