In this review, we synthesize the current state of knowledge by examining experimental findings, theoretical formulations, and numerical simulation techniques relevant to sorption-induced deformation in porous media. To begin with, experimental studies on both mesoporous and microporous systems are summarized, revealing that the deformation response strongly depends on pore size, thereby pointing to distinct physical mechanisms operating at different scales. Subsequently, theoretical approaches that have been developed to rationalize sorption-induced deformation are considered. These models aim to describe adsorption-induced stresses originating from a variety of microscopic processes and to incorporate them into macroscopic constitutive relations capable of predicting the resulting deformations. Furthermore, numerical strategies devised to simulate this coupled phenomenon are outlined, encompassing methodologies that vary according to the scale of the pores and the level of material description. Ultimately, by assessing the current achievements and limitations, the review highlights persisting knowledge gaps and identifies critical directions for future research into sorption-induced deformation.</p></div>","PeriodicalId":50892,"journal":{"name":"Acta Mechanica Solida Sinica","volume":"39 4","pages":"373 - 387"},"PeriodicalIF":2.7,"publicationDate":"2026-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147733211","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 principle of energy conservation, a theoretical model was developed to describe droplet rebound on anisotropic superhydrophobic surfaces, providing functional relationships between the rebound direction and velocity of the droplet and the structural characteristic parameters. Combined with numerical simulations and experimental characterization, it was found that a stable Cassie state reduces energy dissipation during the droplet spreading and rebound process, facilitating low energy rebound. Moreover, under different parameter conditions, droplets can exhibit completely opposite motion on anisotropic surfaces. With the increase of the proportion of structures in the Wenzel wetting state, the droplet rebound direction gradually shifts from opposite to the structural inclination to the same direction. Furthermore, the droplet spreading and rebound process is primarily influenced by the droplet’s initial state and the surface compressive stability. Through force-material optimized design, the fabricated biomimetic surface enables droplets to maintain a Cassie state with minimal energy dissipation even at <i>We</i> = 18, reducing the required Weber number by 35% compared with the rebound distance in the Wenzel state.

Distinguished from previous elastic media, this work combines finite element simulations and experiments to investigate directional flexural wave propagation in viscoelastic PnC plates. The sample of cross-shaped viscoelastic PnC plate is fabricated from epoxy resin with characterization of viscoelasticity by Kelvin-Voigt model. Firstly, non-negligible discrepancies of wave attenuation are observed between complex band structures of unit cell and transmission spectrum of finite PnC plate. In comparison, complex dispersion and modal analysis on the basis of supercell more accurately capture the wave attenuation ranges. Secondly, both simulations and experiments confirm the phenomena of flexural wave propagation along either single or two orthogonal directions. The complex band structures of supercell are employed to help predict the spatial attenuation of evanescent wave within directional bandgaps. The characterization results, with combination of low-order evanescent modes, agree well with numerical simulations and experimental measurements. In addition, the orthotropy index and concentration index of wave transmitting are proposed to evaluate the directional wave propagation. For wave transmitting in a single direction, there is significant and positive correlation between concentration index along the propagating direction and the imaginary part of wavenumber along its orthogonal direction. This work could shed light on the directional propagation of flexural waves, which is beneficial to the design of viscoelastic devices and waveguides.</p>\u0000 </div>","PeriodicalId":50892,"journal":{"name":"Acta Mechanica Solida Sinica","volume":"39 4","pages":"521 - 533"},"PeriodicalIF":2.7,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147733070","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 nonlinear evolution of key parameters, including three-dimensional strain, fracture strength, total energy, and diffusion coefficients during ion insertion, migration, and aggregation is analyzed. The results show that with increasing lithium concentration, the total energy of the system decreases gradually, while the diffusion capability is significantly reduced; the three-dimensional strain of the microstructure exhibits anisotropy, with slow in-plane expansion and abrupt interlayer dilation, accompanied by a pronounced decrease in fracture strength and ductility of the staged structures. Based on that, this study further discusses the synergistic and bidirectional coupling effects between electrochemical evolution and mechanical response: higher lithium concentration causes energy reduction, diffusion limitation, and mechanical degradation, while structural deformation and mechanical degradation in turn restrict ion migration pathways. These findings reveal the intrinsic correlations among phase transitions, structural evolution, and performance degradation.
