Research on dynamic polymers and polymer gels has developed several novel mechanisms beyond the swelling mechanism. These novel mechanisms also enable dynamic polymers to undergo shape transformations over time within a solution environment. Specifically, under certain environmental conditions, monomer solutions can undergo monomer insertion and facilitate the formation of new polymer chains. This process endows the polymer gel network with self-growing characteristics, making it better suited to meet the demands of applications in engineering. Introducing anisotropy into hydrogels makes it possible to meet the demands for non-uniform deformation of polymer gel structures in many scenarios, thereby facilitating the programmable anisotropic swelling. Although the potential applications of these technologies are extensive, many aspects of the self-growth and swelling deformation behaviors in anisotropic polymer gels remain underexplored. A micro-theoretical investigation into the self-growth process of fiber-reinforced polymer gels is proposed. The embedding of fibers within the growable polymer matrix is shown to guide the material toward exhibiting overall anisotropic behavior. To describe this response in detail, a constitutive model for self-growing fiber-reinforced polymer gels was developed and implemented through numerical simulations, which provides a theoretical foundation for predicting the complex deformation behaviors of anisotropic biomaterials.</div></div>","PeriodicalId":281,"journal":{"name":"Composite Structures","volume":"360 ","pages":"Article 119020"},"PeriodicalIF":6.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143580619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, a fully coupled nonlinear electro-magneto-thermo-elastic constitutive relationship is established. Based on finite volume direct averaging micromechanics (FVDAM), the local stress, electric displacement and magnetic flux density distribution of discrete elements are obtained by constructing the generalized local stiffness matrix and assembling the global stiffness matrix. The equivalent material coefficients of the magnetoelectric composite are obtained by employing the homogenization technique. Results of the numerical model are compared with different discrete elements and experimental data to verify the convergence and effectiveness of the developed algorithm. Moreover, effects of external prestress, ambient temperature, microscopic structure and applied magnetic field intensity on material properties such as magnetoelectric and piezomagnetic coefficients are investigated. Finally, the influences of initial damage and constituent phase volume fraction on the equivalent material coefficient and local mechanical response are discussed.

We developed a new finite interface element considering interface curvature dependence and established a simulation method for calculating the Young’s modulus and yield strength of NPRCs. We investigated the impact of nanoparticle modulus, geometric distribution, and interface effects on the Young’s modulus, yield strength, and energy absorption characteristics of NPRCs. The results indicate interface bending stiffness moderately enhances the Young’s modulus of NPRCs, but this enhancement diminishes as particle modulus increases. Additionally, the Young’s modulus of NPRC usually increases with the addition of particles, thus, significant particle agglomeration markedly reduces it. Furthermore, interface bending stiffness increases strain energy density in NPMs but decreases its energy absorption efficiency. The thin-walled structure within nanoporous materials (NPMs) is particularly susceptible to buckling under external loads, which markedly increases dependence of yield strength on surface bending stiffness.
