应用横观各向同性材料模型的钢缆接触分析 Title:AnalysisofContactbetweenSteelCablesusinganIsotropicMaterialModel Introduction: Theanalysisofcontactbetweensteelcablesusinganisotropicmaterialmodelisanimportantaspectofstructuralengineering.Steelcablesareextensivelyusedinvariousapplications,includingsuspensionbridges,cable-stayedbridges,andelevatorsystems.Understandingthecontactbehaviorbetweencablesiscrucialforensuringthesafetyandreliabilityofthesestructures.Thispaperaimstoinvestigatetheapplicationoftheisotropicmaterialmodelinanalyzingthecontactbetweensteelcables.
