WebThe results provided a detailed understanding on the effect of decreasing temperature to the steady‐state fracture toughness K∞ that only the increase in the transformation toughening shielding term ΔKT contributed to the K∞ value at cryogenic temperatures, whereas the intrinsic fracture toughness K0 is independent of temperature. WebThus, finding an effective way to assemble the graphene nanosheets while not impacting its intrinsic properties is challenging. In nature, ... The fracture toughness is 3000 times higher than natural aragonite minerals owing to the "extrinsic toughening mechanism" from the crack deflection and bridging in the "brick-and-mortar" architecture.
