Characterizing the particle order parameter is a prerequisite for studying the properties of the system. The order parameter of arbitrarily shaped particle can be characterized by Wigner D-matrices or the super-tensor basis, and the super-tensor basis more clearly explains the physical meaning of the order parameter. However, the expressions for the super-tensor basis are complex, and explicit expressions for orders higher than three are rarely provided in the literature. This paper reveals the relationship between the super-tensor basis and the projection operators, which decomposes symmetric tensors into irreducible tensors. Explicit expression for the projection operator is provided, and the consistency with the existing recursive expression and differential expression is demonstrated. Based on this, the expression for super-tensor basis of any order is derived, and the orthogonality of super-tensor basis is provided. Finally, the sound propagation in a biaxial super-ellipsoid particle system is simulated by the discrete element method, and the sound velocity is also calculated. The results indicate that different arrangement structures can affect the sound velocity. From the perspectives of order parameter and elastic moduli, the differences in sound velocities of different packing structures are explained. The explicit expressions of the projection operator and the super-tensor basis provided in this paper facilitate the convenient calculation of the anisotropy of other physical quantities within the system, which can be utilized to elucidate the macroscopic mechanical properties of the system.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"311 ","pages":"Article 113257"},"PeriodicalIF":3.4,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387927","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}

However, the temperature-sensitive and history-dependent stress-softening effect during cyclic loading–unloading processes cannot be adequately described by the existing theoretical models. In this study, an anisotropic hyper-visco-pseudoelastic damage constitutive model that considers the temperature effect is established to examine the cyclic stress-softening effect and residual-deformation behavior of FRFCs. This model combines the hyper-visco-pseudoelastic theory and continuum damage mechanics while incorporating the influence of temperature. To quantify the degree of damage during cyclic loading–unloading processes, an anisotropic damage evolution law that satisfies thermodynamic constraints is proposed. Additionally, it has been demonstrated that a comprehensive consideration of viscoelasticity, pseudoelasticity, and the damage effect is crucial for accurately describing the cyclic stress-softening effect. Furthermore, a numerical computational framework is presented to analyze the cyclic softening effect and residual deformation in FRFCs and flexible structures. The effectiveness of the constitutive model and numerical computational framework are validated by conducting cyclic loading–unloading experiments at different temperatures. A good agreement is observed between the results of theoretical calculations and numerical simulations and experimental data, confirming the advantages of the proposed constitutive model and numerical computational framework in accurately describing the softening effect and residual deformation of FRFCs, soft biological tissues, and flexible structures with complex structural forms. This study provides theoretical guidance and numerical computation techniques for improving the performance stability of FRFCs and novel flexible structures.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"311 ","pages":"Article 113254"},"PeriodicalIF":3.4,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143166723","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}

Based on the nonlinear electroelasticity theory, the deformation of the structure characterized by the Gent ideal dielectric model is elaborated. The strain–stiffening enables the bilayer tube to resist large deformation and enhances the tunability under inhomogeneous biasing fields. In order to analyze the dynamic behaviors of circumferential shear horizontal (CSH) and Lamb–like (CLT) waves, the Legendre polynomial expansion method (LPEM) is combined with the linearized incremental equations to derive the dispersion relation. It overcomes the difficulties of conventional matrix methods in dealing with radial dependent electroelastic moduli and shows good convergence. Numerical results demonstrate that the pre–stretch, voltage and strain–stiffening can change the geometry and electroelastic moduli of the dielectric tube, which exhibit the potential to tune the propagation behaviors of circumferential waves. In addition, dispersion properties of circumferential waves are sensitive to the voltage change, which indicates that the dielectric bilayer tubular systems can act as voltage–controlled elastic wave actuators and sensors.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"311 ","pages":"Article 113247"},"PeriodicalIF":3.4,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143166721","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 smeared crack formulation is incorporated into the fiber kinking model and seamless coupled with the transverse damage evolution model to address combined loading modes and mixed mode loading.

We show that by activating the viscoelasticity of the stiffer layer with an increasing strain rate, one can promote the early development of the buckling (the critical strain decreases as the strain rate is increased). The tunability of the critical strain is bounded by the limits for fast and slow loading rates.

The energy-dissipating property of shape memory alloys (SMAs), associated with their underlying phase transformation, can help enhance the overall damping capacity while maintaining required stiffness performance. However, the design of the core poses significant challenges due to the highly nonlinear behavior of SMAs. In this work, an optimization framework for the design of nonlinear sandwich beams with SMA cellular cores is presented. The approach relies on a combination of a deep learning (DL)-based surrogate model with an evolutionary optimizer. While trained on a limited number of configurations, the surrogate model can accurately predict the nonlinear response of the SMA sandwich beam (SSB) integrating an arbitrary core design, accelerating the nonlinear numerical simulations by six orders of magnitude. Then, by incorporating the surrogate model into an evolutionary algorithm, the multiobjective optimization problem can be solved under geometric constraints. In particular, optimal core designs are sought to maximize damping while simultaneously satisfying stiffness and SMA volume requirements. The obtained optimal configurations are then validated via full field finite element analysis, showing that the proposed framework can effectively deliver SSB designs with tailored performance.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"311 ","pages":"Article 113223"},"PeriodicalIF":3.4,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143167721","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}
