Uniaxial tensile tests are carried out for 22 steel and aluminum sheet metals with different thicknesses to characterize their mechanical properties, such as the Young’s modulus, yield stress, strength, strain hardening, etc. Approximately 20–30 three-point bending tests are conducted for each sheet metal with different gaps and punch strokes to obtain different bending angles before and after spring-back ranging from 60° to 165°. The angles after spring-back are modeled by an ANN as the output. The inputs for the ANN model include the mechanical properties obtained from uniaxial tensile tests, as well as gap and punch stroke used in three-point bending. The angles after spring-back predicted by the ANN model trained by 22 materials are compared with experimental results to evaluate its performance. The comparison shows that the trained ANN model can precisely predict the angle after spring-back with a maximum error of less than 3.7%. The trained ANN model is also tested for unseen gap and stroke, to design the processing parameters in three-point bending of advanced high-strength steel (DP980) and an aluminum alloy (AA6K21-T4). The application demonstrates that the trained ANN model can design the process parameters with high accuracy even for unseen data. This study shows that the ANN model is strongly suggested to be used in process and tool design/optimization of metal forming processes to achieve high accuracy and generalizability.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"42 3","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To our knowledge, this is the first such analysis on fibril-reinforced biological tissue. Twenty-seven sutured human meniscal horns (65 ± 6 years old; 17 female, 10 male) were indented at 7 points each and subjected to 3 traction levels: unloaded, 10 and 20 N. Eighty-four FE models of one specimen simulated the 7 indentations under the 3 tensile levels, applying 4 different material models strategies derived from indentation outcomes of specific specimen unloaded, specific specimen at maximum traction, mean of 27 specimens unloaded and mean of 27 specimens at maximum traction. Indentations showed increases for both traction levels from the unloaded state in maximum force (<i>p</i> = 0.02 for 10 N; <i>p</i> = 0.007 for 20 N), instantaneous modulus (<i>p</i> = 0.002 for 10 N; <i>p</i> < 0.001 for 20 N) and relaxation modulus (<i>p</i> < 0.001 for 10 and 20 N). No differences were found between the loaded levels. FE models using properties from indentation tests under traction conditions similar to the simulated one provided more accurate predictions, being more precise when using specimen-specific data. Therefore, indentation outcomes of sutured meniscal horns are affected by fiber-directional traction.

However, current studies have predominantly focused on the domain of acoustic waves. Compared to acoustic waves, elastic waves are vector waves, making their study more complex and challenging. Therefore, achieving higher-order topological states in elastic waves holds significant research value. In this paper, we proposed the design of an intelligent topological metamaterial, which is composed of magneto-rheological thin layers and an elastic substrate. First, by adjusting the topological structure, we successfully excited first-order topological states of Lamb waves in numerical simulations. Subsequently, we constructed a two-dimensional topological structure to excite zero-order topological corner states. Given the unique advantages of magnetic fields in regulating material properties and behaviors, we investigated the effects of magnetic fields as an external control mechanism on Lamb waves in magneto-rheological materials. Our analysis focused on the regulation of Lamb wave topological edge states and corner states via magnetic fields. The results demonstrate that by varying the magnetic field strength, we can precisely control the characteristics of the topological states. Magnetic field modulation of the topological states in Lamb waves enables the realization of non-contact, controllable phononic devices, which is of great significance for the development of topological acoustics.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"42 3","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanical characteristics of the materials vary in all three directions of length, width, and thickness of the plate according to the exponential law. Additionally, it has viscoelastic behavior according to the Kelvin-Voigt model. The novelty of this paper lies in the incorporation of the spatial variability of nonlocal and length-scale factors as additional mechanical characteristics of the material. The overall equation of motion for the plate is derived by including the classical plate hypothesis and Hamilton’s principle. A quadrilateral plate element with four nodes and six degrees of freedom is created using a non-conforming <i>C</i><sup>2</sup>-level Hermitian function.

First, one-borehole blasting was used to reproduce the crack propagation results under free and non-reflecting boundaries, and the good results provided compelling evidence of the reliability of this strategy. For the two- and three-borehole blasting, it was discovered that high confining pressure paired with the large time interval was not favorable for crack coalescence. Therefore, simultaneous initiation is an optimal plan, which is not dependent on time interval and confining pressure. Simultaneously, if the borehole distance remains unvaried, the predominant influence on crack coalescence transitions from the time interval to the confining pressure as these two factors increase. Moreover, crack coalescence takes place when the tensile stress field of one crack is not converted into the compressive stress field of another crack, and crack coalescence has two key mechanisms: mutual and indirect modes.

The stress and displacement fields are influenced by the structure’s geometrical configuration, material properties, and bonding conditions at the interfaces between adjoining layers. In this study, we investigate the mechanical response of a perfectly-bonded multilayer structure under normal loading using the Fourier transform. The normal loading is decomposed into symmetric and antisymmetric cases based on the linear superposition principle. Closed-form solutions are obtained in the formation of Fourier integrals with the associated coefficients being determined by the boundary conditions. The effects of Poisson’s ratio, shear modulus, and thickness on the stress distribution and maximum displacement are studied. For a two-layer structure, plastic deformation is most likely to initiate in the soft layer near the interface in the presence of a large shear moduli ratio between the two layers. Although the average normal displacement increases as the soft layer thickens, regardless of the shear modulus ratio, it may not increase monotonically with the total thickness, particularly when the shear modulus ratio is small. Under the thin film approximation, the response with uniform normal loading can be used to estimate the response of the indentation problem.
