In this study, we present a novel approach to achieving synergistic effect between strength and toughness by constructing graphene origami/aluminum nanocomposites (GOri/Al). Molecular dynamics (MD) simulations were applied to investigate the nanoindentation behavior and reveal the strengthening and toughening mechanisms of the GOri/Al. The results show that compared to graphene/aluminum composites (Gra/Al), GOri/Al exhibits a 35 % enhancement in fracture toughness and a 22 % improvement in load-bearing capacity respectively. In the Gra/Al, the graphene fails and fractures at an indentation depth of 49.8 Å, resulting in the loss of reinforcement. In contrast, the GOri in the GOri/Al remains intact at an indentation depth of 55 Å with a unique unfolding process. After the indenter is completely unloaded, the GOri/Al shows significantly reduced dislocations and excellent plastic recovery. In the elastic stage, the speed of dislocation nucleation in different systems is the main factor affecting the indentation force. When the diamond indenter begins to interact with the insertion layer, the C-C bond stretching tension in the graphene causes a significant increase in indentation force, while the GOri is still in its buffering phase. In the plastic stage, stress in the GOri/Al is distributed along the periphery, with the ridges of the folds bearing more stress, effectively relieving stress concentrations. Adding a GOri together with a graphene of the same size to the Al further enhances the composite flexibility, strength, and hardness. Finally, the effects of indenter speed and indenter radius on the mechanical properties of the GOri/Al are also investigated. Our study provides a novel theoretical analysis and approach for the development of new Al nanocomposites.</div></div>","PeriodicalId":18296,"journal":{"name":"Mechanics of Materials","volume":"207 ","pages":"Article 105381"},"PeriodicalIF":3.4,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144116242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, capturing the strength and fracture behavior of GMs presents challenges, as the extent to which classical theories for homogeneous materials apply remains uncertain. For example, it has been recently suggested that in the classical problem of a sharp wedge or crack loaded in-plane (mode I and/or mode II), the stress singularity can be mitigated by grading the elastic properties of the material near the notch tip according to a power-law distribution, <span><math><mrow><mi>E</mi><mo>∼</mo><msup><mrow><mi>r</mi></mrow><mrow><mi>β</mi></mrow></msup></mrow></math></span>. This suggests that sharp geometrical discontinuities can exist without causing sharp stress concentrations. Under these conditions, it is conceivable that structural optimization should aim to achieve uniform stress distribution or, more specifically, consistent strength throughout the material. Since material resistance typically follows a power-law function of the elastic modulus, a state of uniform stress is not optimal. However, a state of uniform strength may also be considered less than ideal with respect to the homogeneous material since the softer material used to reduce stress concentration reduces also the strength of the specimen. Here, we report experiments conducted on V-notched specimens, varying the grading exponent <span><math><mi>β</mi></math></span>, and compare the results for homogeneous material specimens with those of GMs. We find that the cancellation of singularity effect competes with the reduction of strength due to the use of softer materials, but when the latter effect is accounted for or reduced, we observe an improvement compared to the homogeneous V-notched case. Further, when the strength-modulus exponent <span><math><mrow><mi>m</mi><mo>=</mo><mn>0</mn></mrow></math></span>, structural optimization is equivalent to minimizing stress concentration.
