Özet

Monotonic tensile tests are conducted on seven different Glare grades of fiber metal laminates. In-situ stress-strain curves of glass/epoxy laminate interleaved in Glare 2(3/2) are exposed with the application of metal volume fraction method using the stress-strain curves of Glare 2(3/2) and Aluminum 2024-T3 in unidirectional and transverse directions. The strain-stress curves of cross-ply Glares are predicted by the modification of this method with an empirical parameter and a second parameter considering the relative glass/epoxy laminate thickness ratios of Glare grades. Modified metal volume fraction method presented in this study can be used as a preliminary estimation of stress-strain curves of multiple possible fiber metal laminate configurations without testing.
