Special Issue Information

Dear Colleagues,

Mechanical modeling and analysis is a core technology in civil engineering, used for achieving material innovation and structural safety. By establishing precise mathematical models, engineers can simulate the mechanical responses of construction materials such as steel, concrete, and composite materials under the coupling effects of load, temperature, corrosion, and other factors in a virtual environment, providing a quantitative basis for optimizing strength and enhancing the durability of new materials. In addition, this in-depth analysis lays the theoretical foundation for the development of novel materials like metamaterials. Through accurate simulations of their mechanical properties under various conditions, researchers can gain a deeper understanding of these materials' unique characteristics and optimize their design for specific applications, paving the way for breakthroughs in material science. This Special Issue brings together mechanical modeling and the analysis of materials and structures in the field of civil engineering. The papers collected in this Special Issue can help researchers, engineers, and scientists to find advanced mechanical analysis methods and provide ideas for the search for new materials.

The purpose of this parametric study was to develop a numerical simulation model calibrated with experimental data to predict the flexural behavior of prestressed concrete (PSC) girders subjected to long-term prestress losses. The model is capable of accurately simulating the flexural behavior of PSC girders using commercial finite-element (FE) software in the ABAQUS/Explicit program. The accuracy of the model was validated by comparing its results with flexural response test data from three post-tensioned girders, with the tendons ultimately having tensile strength capacities of 1860 MPa, 2160 MPa, and 2400 MPa. The comparison demonstrated generally excellent agreement between numerical and experimental results in terms of the load–deflection response and crack propagation behavior, from the onset of first cracking through the maximum load and into the ductile response range. Subsequently, a parametric study was conducted to evaluate the effects of tendon ultimate strength, amount of long-term prestress loss, grouting defects, degradation-induced reductions in concrete strength, and reductions in tendon cross-sectional area on girder flexural behavior. Through this parametric investigation, the study identified key factors with respect to long-term prestress loss that may influence the flexural behavior of aging PSC structures. Full article

An exact analytical model based on three-dimensional (3D) thermo-elasticity theory is developed to investigate the bending behavior of fiber metal laminate (FML) plates under thermo-mechanical load. The temperature-dependent properties and the orthotropy of the component materials are considered in this model. The analytical model is based on the heat conduction theory and thermoelasticity theory, and the solutions are determined by employing the Fourier series expansion, the state space approach and the transfer matrix method. Comparison study shows that the FE results are generally in good agreement with the present analytical solutions, exhibiting relative errors of less than 2%, except in the regions near the upper and lower surfaces. The present solution is close to the experimental values for the laminated plate within the linear range, with errors less than 10%. The decoupling analysis indicates that the thermo-mechanical performance of FML plates no longer strictly adheres to the traditional superposition principle, with errors reaching 30.39%. A modified principle accounting for modulus degradation is introduced to address this discrepancy. Furthermore, parametric studies reveal that the temperature and the lamina number have significant effect on the stresses and displacements of the FML plate. Full article
