This study presents comparative collapse tests on two modular steel substructures: specimen in corner column loss (S-CCL) and specimen in side column loss (S-SCL). The failure modes, load-bearing capacities, lateral displacements of modules, relative slips of double-layer beams, and deformation mechanisms of the components were compared. The findings reveal significant buckling at the ends of module beams far from the column loss area in both specimens, with minor buckling near the column loss area. No bolt hole fracture is observed in S-CCL, while S-SCL exhibits clear fractures. S-SCL demonstrates approximately double the load-bearing capacity of S-CCL during the elastic stage, and this increases further in the elastoplastic stage due to catenary action, ultimately reaching three times that of S-CCL. Significant lateral displacement occurs only in the double-span beam direction of S-SCL, towards the column loss area, while in other directions, displacement is minor and directed away. Digital image correlation (DIC) measurements indicate that relative slip in double-layer beams is significantly smaller in S-SCL compared to S-CCL. Strain gauge readings show that both module columns remain within the elastic range, but columns in S-SCL continue to deform in the plastic stage due to tensile forces in the connected beams, with beam ends away from the column loss area experiencing negative bending moments.</div></div>","PeriodicalId":49435,"journal":{"name":"Thin-Walled Structures","volume":"206 ","pages":"Article 112695"},"PeriodicalIF":5.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661813","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}

The optimization problem is innovatively formulated based on the definition of a ground laminate with redundant layers. The basic optimization idea is to seek both unnecessary and necessary layers in this ground laminate. For unnecessary layers, they can be removed and assigned with small-value ply thicknesses, while necessary layers are retained in the ground laminate and corresponding ply thicknesses and fiber angles are optimally determined using discrete and continuous variables, respectively. Since variable-stiffness composite laminates always require high-fidelity analysis models to accurately capture the spatial characteristics of varying fibers, this results in a time-consuming process. To alleviate this problem, a multi-fidelity surrogate model with an exponent-based comprehensive correction is originally proposed based on Gaussian process regression, generating an approximate problem to replace the original one. The genetic algorithm and sequential quadratic programming method are sequentially employed to solve this approximate problem with mixed design variables. The solution from this procedure is dynamically added to the sampling dataset to update the constructed surrogate model. Numerical benchmark problems and cases studies of a composite plate and a solar wing structure are addressed, demonstrating the efficacy of the newly proposed optimization strategy.</div></div>","PeriodicalId":49435,"journal":{"name":"Thin-Walled Structures","volume":"206 ","pages":"Article 112392"},"PeriodicalIF":5.7,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663881","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}

The AMLS achieves precise shape, internal structure, and stiffness, ensuring the decided structural performance with minimum materials. This study provides a theoretical model of HLFP, focusing on adhesively bonded AMLS. The experimental verification demonstrates that the adhesively bonded AMLS ensures an additional 130 % during the elastic stage and, even after partial debonding, maintains 50 % of the mechanical resistance compared to the theoretical sum of the HLFP components. Reducing the infill density does not severely affect the load-bearing capacity of the HLFP—a fourfold decrease of the ALMS density (from 10 % to 2.5 %) results in a 20 % decrease in the ultimate load. However, the sparse lattice structure alters the failure mechanism of ALMS, changing it from favorable ductile to dangerous brittle and determining the object for further optimization. The parametric study reveals the efficiency of the theoretical model for predicting the load-bearing capacity of HLFP.

Each plate comprises three layers: a homogeneous hard core and two FGM face sheets, divided horizontally into two segments with differing face sheet thicknesses, which enhance structural stiffness while maintaining a consistent total thickness. The material properties of the sandwich plates follow a power-law distribution. The formulations are based on higher-order shear deformation plate theory and von Kármán geometric nonlinearity, and are solved using Galerkin’s method.

A new graphical user interface (GUI) tool facilitates frequency predictions using the proposed ANN model. Key findings indicate that modifications to the stepped face sheets and core layers affect stiffness, natural frequency, and vibration amplitudes. Increasing the core-to-total thickness ratio enhances stiffness, resulting in higher frequencies and reduced displacement amplitudes.

Besides, the relationship between the crystal orientation in engineering and material science is clarified by a mathematical approach. Primary orientations characterized by two deviation angles, each having 16 directions and secondary orientations with 11 deviation angles are defined by three angles measured by the Laue method. Good agreement on variation of structural eigenfrequency for the first bending or torsional mode is attained between theory analysis and numerical calculation. Numerical results show that the primary orientation deviation direction could cause significant dispersion of the natural frequencies for low and high order modes. The increasing deviation angle widens the dispersion, with the maximum variation ratio of 5.62% for the torsional mode. Importantly, the conjunction with the secondary orientation could further changes the dispersion of the natural frequencies, and the maximum variation of 6.5% is achieved for the torsional mode.
