Specific deformation control can be achieved by applying multiple voltage layouts to the surface of a piezoelectric structure.

This study introduces a topology optimization approach for precise deformation control of piezoelectric structures with multiple voltage layouts, leveraging a multi-material topology optimization model. In this method, the objective function is defined as the weighted sum of deviations between the actual and target deformation shapes, providing a measure of discrepancy. Different actuating voltages, including zero voltage across all piezoelectric finite elements, are selected as design variables to achieve an optimal multi-voltage layout for arbitrarily specified structural deformations. The Discrete Material Optimization (DMO) interpolation model, combined with the Heaviside projection function, is used to implement multi-voltage selection and filtering during optimization. Explicit sensitivity analysis of the objective and constraint functions with respect to the design variables is derived, and the optimization problem is solved using mathematical programming algorithms. Numerical examples validate the effectiveness of the proposed optimization algorithm in accurately controlling various pre-specified deformation shapes.

The study shows that as λ increases and θ decreases, the peak pull-out load of the Z-pin reinforced laminate gradually increases. Meanwhile, increases in λ and θ significantly enhance the critical mode I (G<sub>IC</sub>) and mode II (G<sub>IIC</sub>) interlaminar fracture toughness. When λ = 60 n/m and θ = 60°, G<sub>IC</sub> is 4764.75 J/m<sup>2</sup>, which is 6.78 times greater than that of the blank specimen.

However, the out-of-plane flexibility of the conventional re-entrant honeycomb (CRH) cannot be improved without compromising flatwise stiffness. To overcome this limitation, a novel gradient re-entrant honeycomb (GRH) design that incorporates horizontal ligaments is introduced. A multiscale constitutive framework is established using the variational asymptotic method to model complex GRH structures. This framework results in a three-dimensional equivalent Cauchy model (3D-ECM) for multicellular GRH and a two-dimensional equivalent plate model (2D-EKM) for GRH panels. The efficacy and accuracy of these equivalent models are confirmed through uniaxial compression and tensile tests on 3D printed multicellular GRH specimens, complemented by numerical simulations evaluating the out-of-plane and in-plane behaviors of GRH panels. Compared to the CRH, the GRH demonstrates a 23.0% reduction in out-of-plane elastic modulus and a 66.7% increase in in-plane elastic modulus. The optimal GRH parameters — re-entrant angle of 80°, horizontal ligament-to-inclined wall length ratio of 1.2, wall thickness ratio of 0.15, and horizontal ligament-to-cell height ratio of 0.4 — ensure high in-plane stiffness, out-of-plane flexibility, quasi-ZPR, and low effective density, making the structure ideal for lightweight, high-performance applications.</div></div>","PeriodicalId":49435,"journal":{"name":"Thin-Walled Structures","volume":"213 ","pages":"Article 113241"},"PeriodicalIF":5.7,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143785455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing thin-sheet KM designs face two major challenges, including loss of auxeticity due to out-of-plane bucking at high strains and anisotropic auxetic behavior limited to a single loading direction. This study proposes an optimization method to design innovative KMs with square-symmetric auxeticity. That is, the designed KMs possess consistent negative Poisson's ratios under large uniaxial stretching as independently loaded from two orthogonal directions. This is achieved by enforcing both mirror and rotational symmetries to the KM unit cells, which ensures identical geometries as viewed from these two directions. A structural optimization problem is formulated to determine cut shapes that can achieve desired negative Poisson's ratios under large stretching, considering potential out-of-plane buckling and yielding failures that affect in-plane properties. To avoid cut intersections, three distinct design domains are defined to constrain the movement of the control points.

The stress and strain distribution and forming characteristics during reshaping were analyzed, and the mechanical properties and failure mechanisms of SPR and RSPR joints were compared. The results show that the reshaping method significantly reduces the bottom protrusion height and guides secondary flaring of the rivet. After reshaping, the maximum shear strength increased by 20 % for the pip die and 28 % for the flat die, while peel strength improved by 24 % and 25 %, respectively.

These openings result from the cutting and welding of the I-section, increasing its height and second moment of area about the strong axis. However, the beam's torsional stiffness reduces and other failure modes may arise. Lateral-torsional buckling (LTB), a widely studied type of global stability failure mode, is more likely to occur in these beam models due to the expansion of the section after cutting and welding to form openings in the web. On the other hand, web-post buckling (WPB), a type of local stability mode, occurs in the web region between the openings, and this is a failure mode exclusive to perforated cross-sections. While both failure modes have been extensively addressed in the literature individually, limited attention has been given to their interaction, underscoring the need for further investigation of cellular beams under these conditions. Therefore, this paper aims to assess the interaction between LTB and WPB exclusively in cellular beams. The proposed approach involves developing a design curve using the Direct Strength Method (DSM). Based on the analyses of 120 models, results indicate that a significant set of the studied members fail only due to LTB, while others fail due to WPB or due to the interaction between the two failure modes. Thus, a DSM-based curve was proposed to obtain the normalized ultimate bending moment of beams susceptible to interaction-driven failure modes with respect to the LTB resistance moment.
