Time-dependent rheological behavior of branched polymer melts in extensional flows 作者:Wang, W (Wang, Wei)[ 1,2 ] ; Hu, CX (Hu, Changxu)[ 1 ] ; Li, WW (Li, Wenwen)[ 1 ] MECHANICS OF TIME-DEPENDENT MATERIALS 卷: 20 期: 1 页: 123-137 DOI: 10.1007/s11043-015-9287-3 出版年: FEB 2016 查看期刊信息 MECHANICS OF TIME-DEPENDENT MATERIALS 出版商 SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS ISSN: 1385-2000 eISSN: 1573-2738 研究领域 Mechanics Materials Science 摘要 The viscoelastic flow of low-density polyethylene melts in a cross-slot channel is studied numerically for the double convected Pom-Pom (DCPP) and single modified DCPP (S-MDCPP) models. The equal low-order finite elements for velocity-pressure-stress variables are implemented to solve the flow fields using the pressure-stabilized iterative fractional step algorithm. The distributions of axial velocity along the channel centerline and the principal stress difference achieved by numerical predictions are in quantitative good agreement with the reported experimental results. Furthermore, the evolution of backbone stretch of macromolecule with flow time is demonstrated, and then an exponential decay function is proposed linking the microscale stretch relaxation time with the macroscale flow time, in order to reveal the stretch relaxation response of the branched polymer. The effects of the Weissenberg number and several constitutive parameters of the S-MDCPP model on the rheological behavior of polymer melts are discussed. 关键词 作者关键词:Numerical simulation; Complex flow; Rheological behavior; Extensional flow; Viscoelastic constitutive models; Polymer melts KeyWords Plus:CROSS-SLOT FLOW; PLANAR CONTRACTION FLOW; POM-POM MODEL; FINITE-ELEMENT-METHOD; CONSTITUTIVE MODELS; NUMERICAL SIMULATIONS; POLYETHYLENE MELT; EQUATIONS; RHEOMETRY; FLUIDS 作者信息 通讯作者地址: Wang, W (通讯作者) Qingdao Univ Sci & Technol, Minist Educ, Shandong Prov Key Lab Rubber Plast, Key Lab Rubber Plast, Qingdao 266042, Peoples R China. 增强组织信息的名称 Qingdao University of Science & Technology 通讯作者地址: Wang, W (通讯作者) Dalian Univ Technol, State Key Lab Struct Anal Ind Equipment, Dalian 116024, Peoples R China. 增强组织信息的名称 Dalian University of Technology 地址: [ 1 ] Qingdao Univ Sci & Technol, Minist Educ, Shandong Prov Key Lab Rubber Plast, Key Lab Rubber Plast, Qingdao 266042, Peoples R China 增强组织信息的名称 Qingdao University of Science & Technology [ 2 ] Dalian Univ Technol, State Key Lab Struct Anal Ind Equipment, Dalian 116024, Peoples R China 增强组织信息的名称 Dalian University of Technology 电子邮件地址:ww@qust.edu.cn 基金资助致谢 基金资助机构 授权号 National Natural Science Foundation of China 21274072 11302043 State Key Laboratory of Structural Analysis for Industrial Equipment GZ1213 Key Laboratory of Rubber-plastics, Ministry of Education KF2010007 查看基金资助信息关闭基金资助信息 The authors gratefully acknowledge the financial support from the National Natural Science Foundation of China through Contract/Grant numbers 21274072, 11302043, and the State Key Laboratory of Structural Analysis for Industrial Equipment (No. GZ1213) and the Key Laboratory of Rubber-plastics, Ministry of Education (No. KF2010007). 出版商 SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS 类别 / 分类 研究方向:Mechanics; Materials Science Web of Science 类别:Mechanics; Materials Science, Characterization & Testing 文献信息 文献类型:Article 语种:English 入藏号: WOS:000371303800007 ISSN: 1385-2000 eISSN: 1573-2738 期刊信息 目录： Current Contents Connect® 其他信息 IDS 号: DF4FQ Web of Science 核心合集中的 "引用的参考文献": 38 Web of Science 核心合集中的 "被引频次": 0 影响因子 1.587 1.418 2014 5 年 JCR® 类别 类别中的排序 JCR 分区 MATERIALS SCIENCE, CHARACTERIZATION & TESTING 5/33 Q1 MECHANICS 50/137 Q2 数据来自第 2014 版 Journal Citation Reports® |
