Additionally, it provides the first analytical assessment of the nonlinear forced vibration behavior of composite rectangular sandwich plates with various lattice core geometric patterns under uniform compressive loading. The plate consists of a central lattice core and symmetric homogeneous face plates. Using the first-order shear deformation theory, the partial differential equations of motion are derived via Hamilton’s principle and von Kármán’s nonlinear strain–displacement relations. These equations are then reduced to time-dependent nonlinear ordinary differential equations using the Galerkin method. Primary and secondary resonances are analyzed using the method of multiple scales. The analytically obtained nonlinear primary resonances are validated against the Runge–Kutta numerical method, demonstrating excellent agreement. Secondary resonances, including superharmonic and subharmonic types that introduce new dynamic response frequencies as multiples or fractions of the primary frequencies, are also investigated. These resonances significantly influence the stability and dynamic performance of sandwich plates and play a key role in optimizing their design. This study further examines the effects of key parameters, including rib thickness, core height, and stiffener angles, on vibration amplitude and frequency response curves. The findings, validated through comparisons with existing literature and finite element analysis in ABAQUS, highlight the critical impact of these factors on dynamic behavior and provide valuable insights into design considerations for sandwich plates with lattice cores. </p></div>","PeriodicalId":593,"journal":{"name":"International Journal of Mechanics and Materials in Design","volume":"21 3","pages":"463 - 506"},"PeriodicalIF":3.6,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designing phononic crystals with a target characteristic has become a research hotspot in recent years. Nevertheless, the precision with which the acoustic and mechanical waves can be altered remains a major challenge for existing inverse design methods. The rapidly growing machine learning methods revolutionize the design of these materials. As an important branch of machine learning, reinforcement learning is being attempted to solve mechanical problems more intelligently through the interaction of environment and agent. In this paper, we adopt machine learning to successfully design 2D phononic crystals with expected band structure. We firstly applied the meshless generalized finite difference method in solving the dispersion equation for a periodic structure. Then, in order to widen the first-order bandgap width over a desired frequency range, we employ the reinforcement learning algorithm modified by particle swarm optimization to effectively estimate the shape parameters. The parallel technology saves computational costs remains independent of the initial state and target, in addition to being effective and stable. This improved reinforcement learning based interaction design scheme can easily accommodate several other reverse engineering problems.</p></div>","PeriodicalId":593,"journal":{"name":"International Journal of Mechanics and Materials in Design","volume":"21 3","pages":"547 - 576"},"PeriodicalIF":3.6,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As part of the study, these structures were created using an MSLA 3D printer, and both empirical and computational studies were conducted. Furthermore, the Taguchi method was employed for optimization purposes, and a thorough examination of statistical analyses was conducted. Lattice structures were developed using the SpaceClaim program and produced using the Ancubic M3 MSLA technology, which employs additive manufacturing. The LS-Dyna module of ANSYS Workbench was employed to create the finite element model of the lattice structures, and the manufactured specimens were subjected to compression experiments under the same conditions. The novelty of this work lies in generating MSLA 3D printer strut-based truss structures using both experimental and numerical analysis. Results show that increasing the cell counts also increases the compressive strength and absorbed energy. Similarly, struts and additional supports, which act synergistically, reduce stress concentration and improve stress distribution. Hence, compressive strength and absorbed energy increase.

Displacement constraints are essential in structural design, limiting specific parts of a structure from moving beyond a predefined boundary. To tackle this challenge, an enhanced bi-directional evolutionary structural optimization (BESO) method is proposed. The sensitivity information required for design updates is derived through the adjoint method. This approach leverages the linear perturbation function in ABAQUS, which eliminates the need to compute the inverse of the global tangential stiffness matrix, thereby significantly improving computational efficiency. Python is employed to manage the optimization process, while ABAQUS serves as the finite element solver. Numerical experiments demonstrate the effectiveness and accuracy of the method in optimizing complex 3D structures. The adaptive volume change algorithm stabilizes the optimization process by automatically adjusting volume changes, resulting in a smooth convergence to the optimal solution.
