In the developed structural design, the enhancement of the mechanical response is achieved by locally shortening the beams that caused the intracellular extrusion. Studies that focused on simultaneously strengthening the two above-mentioned characteristics are rarely seen. Unlike the isotropy of the previous GSH structures, the elastic modulus of the reinforced GSH (RGSH) structures in both two principal directions is investigated via performing a complete parametric study. To visualize the utterly different mechanical response between the GSH and RGSH structures, the elastic properties-comparison are presented theoretically, numerically, and experimentally. The developed structural reinforcing method, combining the stiffness and deformability regulation, provides a valuable way to redesign multifunctional lattice structures for meeting the various requirements regarding mechanical characteristics.","PeriodicalId":49186,"journal":{"name":"International Journal of Applied Mechanics","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136271687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A [Formula: see text]-order polynomials approximation is assumed on the beam cross-section for the displacement unknown variables, being [Formula: see text] a free parameter of the formulation. Classical beam theories, such as Euler–Bernoulli’s and Timoshenko’s, are obtained as particular cases. According to the proposed unified formulation, the governing differential equations and the boundary conditions are derived in terms of a fundamental nucleo that does not depend upon the approximation order. The linear static analysis of thin-walled beams is carried out through a closed form, Navier-type solution. Simply supported beams are, therefore, presented. Box, C- and I-shaped cross-sections are accounted for. Slender and deep beams are investigated. Bending and torsional loadings are considered. Results are assessed toward three-dimensional finite element solutions. The numerical investigation has shown that the proposed unified formulation yields the complete three-dimensional displacement and stress fields for each cross-section as long as the appropriate approximation order is considered. The accuracy of the solution depends upon the geometrical parameters of the beam and the loading conditions.","PeriodicalId":49186,"journal":{"name":"International Journal of Applied Mechanics","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135768590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
