Elastic and Mechanical Parameters of n-АМg6/С60 Nanocomposite under Cyclic Reversible Static Load

Results of experimental investigation into the effect of reversible mechanical loading–unloading on linear and nonlinear properties of n ‑AMg6/C60 nanostructured composite are presented. For nanocomposite specimens, mechanical stress–strain curves are measured under many-cycle loading–unloading down to specimen fracture. The effect of cyclic loading–unloading on the microhardness of specimens is investigated. Within different characteristic portions of the stress–strain curve, nonlinear elastic properties of n -AMg6/C60 composite specimens subjected to several loading–unloading cycles are studied by Thurston–Brugger and spectral methods. The results of experimental studies are discussed.
