Phase transformations, carbide precipitation, and recrystallization are examples of the relevant phenomena. Most engineering components require high strength and sufficient residual ductility to withstand mechanical loads and to provide favorable manufacturing conditions. One way to achieve this state is a microstructure composed of bimodal grains. The key contribution of the present manuscript is the proposition of a prototype model for an existing thermodynamic framework, combining two phase-field approaches for the numerical investigation of recrystallization effects. The developed prototype model captures phase transformations, carbon diffusion, and carbide precipitation during static recrystallization. A combined phase-field approach models the microstructure evolution driven by temperature, curvature effects and stored energy effects. The corresponding order parameters are fractions of ferrite, martensite, and carbide phases as well as grain orientation and microstructure crystallinity describing grain boundary movement. The grain boundary evolution is captured by a Kobayashi–Warren–Carter approach. The prototype model builds upon a generalized framework on thermodynamics and captures grain boundary motion in multi-phase continua. This yields a novel constitutive framework capable of describing the complex material behavior of metals during recrystallization annealing. To demonstrate the evolution of phase fractions and carbide precipitation, conclusive two-dimensional phase-field simulations are solved with the finite-element method.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"320 ","pages":"Article 113465"},"PeriodicalIF":3.4,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144213283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two-stage fatigue crack propagation model for Microstructurally-Small Crack(MSC), Physically-Small Crack(PSC) and Long Crack(LC) was developed based on dislocation theory, incorporating cyclic plastic stress correction and crack closure effects. An averaging method was introduced to derive the microscopic parameters within the model, which was subsequently applied to fit fatigue crack propagation data (including short cracks, near-threshold long cracks, and steady-state long crack propagation) for Ti–6Al–4V. The results indicate that the deceleration effect exhibited by MSC at grain boundaries is a critical factor warranting attention. A fretting fatigue test was designed specifically for Ti–6Al–4V, with the contact stress field computed using finite element analysis. The elastic principal stress field at the contact edge can be categorized into three distinct regions based on varying stress characteristics. Fatigue cracks typically initiate in high-stress gradient areas near the contact edge and propagate inward under elevated shear stress within the transition zone. Utilizing this proposed model, predictions regarding Ti–6Al–4V’s fretting fatigue crack propagation life were made; these predictions closely align with experimental findings, predominantly falling within two standard deviations of the scatter band. These results demonstrate that MSC stage propagation significantly influences overall fatigue life under low-load conditions (approaching fatigue limits). This finding underscores our model’s robust explanatory and predictive capabilities concerning fretting fatigue life.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"320 ","pages":"Article 113460"},"PeriodicalIF":3.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144203357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The partially folded BOIII can be recursively extended in the longitudinal direction to form larger tapered tubes. We further introduce a novel transverse extension of the BOIII, enabling the formation of composite BOIIIs with a single degree of freedom. When longitudinally extended, the composite BOIIIs generate rigid-foldable multi-tubular structures. Specifically, we examine plane-symmetric multi-tubular structures and demonstrate the creation of structures with adjustable zigzag and spiral profiles by varying input sector angles. Like the BOIII, these multi-tubular structures exhibit two distinct collapsible or flat states, allowing for compact storage and a large deployment ratio. Both sides of these structures are origami patterns that are free from self-intersection at the initial flat state, facilitating efficient fabrication through folding and subsequent assembly. The resulting multi-tubular structures have potential applications in reconfigurable heat and air conduction tubes, robotic arms, meta-materials, and architectural design.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"320 ","pages":"Article 113452"},"PeriodicalIF":3.4,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144231293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modelling these structures is computationally demanding, and homogenizing their mechanical response is a promising approach to model porous materials. While attention is paid to the elastic response, the yield surface is less discussed, especially in multiaxial loading conditions. In this study, we consider body-centered cubic (BCC) and octet lattice structures as two representative structures, and explore yield criteria for a homogenized model. We use finite element modelling (FEM) to simulate lattices under various loading conditions: uniaxial compression, simple shearing, proportional biaxial and triaxial loadings, and define the yield states based on the principle of equivalent plastic work. Both BCC and octet structures obey anisotropic yielding, while BCC is stronger in shearing than in compression direction, making it more anisotropic. We explore different homogenized yield criteria and find that Liu–Huang–Stout yield criterion, with unsigned mean stress term, is the most comparable to the simulation results. This model, which is anisotropic and considers a linear dependence of mean stress, was found to be the best candidate to describe the multiaxial plastic behavior of lattice structures.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"320 ","pages":"Article 113486"},"PeriodicalIF":3.4,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144239995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
