Figure 4: Fatigue resistance.
From: Super-elastic and fatigue resistant carbon material with lamellar multi-arch microstructure
(a–c) Elastic strength, plastic deformation and energy loss coefficient during 1 × 106 cycles at 20% strain (a), 2.5 × 105 cycles at 50% strain (b) and 1 × 104 cycles at 80% strain (c). (d) Stress–strain curves of C–G monoliths at 20% strain for 1 × 106 cycles, at 50% strain for 2.5 × 105 cycles and at 80% strain for 1 × 104 cycles. (e) Ashby chart plotting stress reduction versus plastic deformation for C–G monolith (10–3.6) and other previously reported materials. Numbers of compression cycle are marked beside the corresponding dots in the chart. Numbers in paranthesis represent relevant references. Per cent values shown to the right of the chart list the relevant compression strain for each finding.
