To illustrate this, we construct both square-shaped and right-angled trapezoidal sonic crystals with a unified lattice design. Unlike the square-shaped structure, the trapezoidal design supports multi-type corner states at distinct frequencies, accommodating obtuse, right, and acute angles. An additional in-gap hypotenuse edge state underscores the versatility of this design.

Here, we study the delamination mechanics of square cross-section elastomers, with a focus on their interface stresses and pull-off forces. Two distinct delamination behaviors are exhibited: edge delamination and center delamination. Edge delamination can be further divided into two elastic-stability patterns, rhombus and finger patterns, with transitions driven by the evolution of stress intensity factor distribution along the interface edge. By introducing two key parameters, the ratio of interface stiffness to material modulus <em>ξ</em> and the width-thickness ratio <em>η</em>, and combining FE analysis, we derive quantitative equations for pull-off forces related to edge and center cracks. Our results show that compared to circular cross-section elastomers, square cross-section elastomers are more likely to transition from center delamination to edge delamination as the edge crack pull-off forces decrease due to high stress concentrations at the corners. Square cross-section elastomers exhibit more sensitive pull-off forces within certain ranges of <em>ξ</em> and <em>η</em>, making them a superior option to circular cross-section elastomers for achieving controlled adhesion.

However, most existing vibration methods for beam structures struggle in dynamic and complex environments due to their continuum nature and nonlinear behavior. To achieve autonomous vibration control across the full spectrum, this article proposes an intelligent excitation adaptability (IEA) concept for real-time vibration control of beam structures under frequency-varying excitations. The IEA system is composed of a stiffness-variable electromagnetic appliance, a real-time excitation frequency recognition algorithm, and an autonomous stiffness-switching program. The electromagnetic appliance, arranged in a nesting-type configuration, consists of six-ring permanent magnets (PMs) and six coil windings (CWs). By tuning the magnitude and direction of the current in CWs, a high (HDS) or low (LSD) dynamic stiffness state can be assigned to the IEA system. We develop a recognition algorithm to rapidly and accurately identify the excitation frequency solely based on displacement response signals derived from a nonlinear dynamic model of the beam. Simultaneously, the autonomous stiffness regulation automatically selects either HDS or LSD mode for optimal vibration suppression. The theoretical and experimental results demonstrate that the frequency recognition and stiffness switching processes of the IEA vibration control (IEA-VC) system are fast (min. to 17 ms), accurate, and reliable. Furthermore, the IEA-VC system significantly mitigates resonance (e.g., from 11.48 dB to -1.35 dB) and achieves full-spectrum vibration suppression compared to traditional vibration control approaches.</div></div>","PeriodicalId":56287,"journal":{"name":"International Journal of Mechanical Sciences","volume":"293 ","pages":"Article 110194"},"PeriodicalIF":7.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761085","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}

Achieving the sound attenuation within a specified frequency range requires an inverse design procedure that refines the geometric parameters of MPP-SCs. Although data-driven methods show considerable promise for solving such inverse design problems, the generation of a large, well-labeled dataset of MPP-SCs remains computationally intensive, posing a critical bottleneck in deep learning-assisted design of periodic structures. To evaluate the acoustic attenuation properties of MPP-SCs, their complex band structures are computed using the Finite Element Method (FEM). In order to enhance computational efficiency, an Interpolated Bloch Mode Synthesis (Interpolated BMS) method is developed within the FEM framework. This method integrates conventional BMS with the matrix interpolation technique. Specifically, the Craig-Bampton method is employed to reduce interior degrees of freedom (DOFs), while a B-spline-based approach is proposed for reducing boundary DOFs. Both steps decrease the dimensionality of the eigenvalue problem involved in calculating the complex band structure, thereby reducing the computational time from 14.86 s to 1.11 s without sacrificing numerical accuracy. Subsequently, matrix interpolation is applied to estimate the reduced global matrices, thereby eliminating the need for re-meshing and re-assembling the matrices when the geometric parameters of the MPP-SCs are adjusted. As a result, the efficiency of training sample generation is enhanced by a factor of 14.4 compared to commercial software. The dataset generated by the proposed method is then utilized to determine the geometric parameters of the MPP-SCs through either meta-heuristic algorithms or a conditional generative neural network.
