| Короткий огляд (реферат): | The influence of stress ratio on functional properties of pseudoelastic NiTi alloy are studied. The changes of residual strain, strain ratio and dissipated energy on the stress ratio of shape memory alloy are investigated. The functional fatigue of the NiTi alloy under the stress-controlled cyclic loading is dependent on the stress range and stress ratio. Dissipated energy and strain range are invariant to the loading cycles for stress ratio 0 and 0.5. When stress ratio increases from 0 to 0.5 at the same maximal stress, the strain range and energy dissipation are decreasing. With the change of the stress ratio from 0 to 0.5 the residual strain in the first and next cycles increases significantly even at lower values of maximal stress. |
