| 1. | Frąś T.♦, Roth M.♦, Pawłowski P., Thermo-viscoplastic behavior of AA7020-T651 in application for modeling of dynamic loadings, ICCEE 2016, International Conference on Civil and Environmental Engineering, 2016-10-17/10-19, Hiroshima (JP), pp.1-8, 2016 Streszczenie: The stress–strain behavior of the rolled AA7020 aluminum tempered in T651 conditions is studied at various strain rates and temperatures. Basing on tensile, shear and compression tests, the effects of strain and strain-rate hardening, thermal softening and plastic anisotropy are discussed. The parameters of the thermo-viscoplastic flow and fracture models proposed by Johnson and Cook are identified and validated basing on the numerical modeling. Słowa kluczowe: AA7020-T651, flow and fracture models, metals under dynamic loadings, numerical simulation of metal deformation Afiliacje autorów:
