Special Issue Information

Dear Colleagues,

Composite materials have been widely used in various applications such as aerospace, marine, automotive structures and other industries due to their high strength and stiffness, extraordinarily low density, excellent environmental resistance and the ability to tailor properties. Many scholars have performed extensive and interesting studies on the nonlinear vibration and structure dynamics of various composite structures, including composite beams, plates and shells. Although some fantastic research breakthroughs have been obtained, there are great challenges in theoretical analysis, numerical simulation, and experimental tests. First, it is difficult to develop an accurate analytical model and a finite element model for predicting the nonlinear vibration phenomena and dynamic parameters of anisotropic materials and structures due to the complexity of geometric and material nonlinearities. Furthermore, experimental investigations on composite materials and structures are quite scarce. However, the models, as well as the predicted results, need to be validated by extensive experimental data, such as nonlinear natural frequencies, damping ratios and dynamic displacements or strains. In addition, a high number of composite materials and structures often serve in multi-field coupling environments, which further increases the research complexity and difficulty. Therefore, these issues will be hot topics and much research effort should be devoted to the above areas for a long time to come.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications and reviews are all welcome.

This study evaluates the API 650 design procedure for steel storage tanks, incorporating nonlinear dynamic analysis with large deformation effects. Focusing on seismic vulnerability, the case study examines storage tanks proposed for construction in Naples, Italy, assessing their performance under site-specific seismic conditions. A target spectrum and 20 earthquake records were selected to reflect regional seismic characteristics. Initial tank thicknesses were calculated using API 650 guidelines and subsequently analyzed through nonlinear time-history simulations in SAP2000. Results reveal that thicknesses derived from API 650s linear average spectrum equations are insufficient for real seismic demands. Through a trial-and-error methodology, optimal thicknesses were determined to ensure satisfactory performance across all seismic records. Key findings highlight significant variations in mode participation, the frequent occurrence of elephant-foot buckling in tanks with lower H/R ratios, and the limitations of linear spectral analysis for realistic earthquake scenarios. Given the vital role of storage tanks in the oil and gas industry, this study emphasizes the need to integrate nonlinear time history analysis into design processes to enhance seismic resilience, particularly in high-risk regions.

This article studies the vibrational behavior of composite conical-cylindrical shells (CCSs) with functionally graded coatings (FGCs) in thermal environments using the first-order shear deformation theory. Firstly, the equivalent material parameters, fundamental frequency, and resonant displacement responses of the CCSs with FGCs are derived using the mixture principle, complex modulus method, and transfer function approach. Then, detailed thermal vibration tests are performed on CCS structures with and without coatings to assess the reliability of the proposed model, revealing that the current model accurately forecasts the thermal vibration behavior of the CCSs with FGCs. Finally, the effect of key parameters on the vibrational properties of the CCSs with FGCs is investigated. The results demonstrate that increasing the functionally graded index, coating thickness, and Young’s modulus ratio can greatly enhance the vibration suppression capability of the structure.
