Cyclic simple shear of metallic sheets: application to aluminium-lithium alloy

  • B. Wack

Plane shear tests without lateral force are obtained with the help of a very rigid shear device, attached to a classical testing machine. To avoid shear strain heterogeneity, essentially in the lateral direction, the shear strain is measured locally. The comparison with tensile test results indicates that for an elongation ratio of 10 the stress is determined with a systematic underestimate of about 4.5%. This shear device allows extensive characterization of an aluminium-lithium alloy, available only in the shape of sheets: the shear modulus of tangential elastic behaviour, conventional yield strength, shear strength of asymptotic plastic behaviour, cyclic hardening and strength anisotropy can be determined. The accuracy of the test, due to the great rigidity of the apparatus, has also permitted determination of the lateral strain and consequently of a shear ratchet during cyclic loadings.
