聚合物材料拉伸性能的模拟研究
Simulation Study of Tensile Properties of Polymer Materials
摘要
Abstract
Polymer materials,with their excellent ductility,play significant roles in fields such as vibration damping and sealing.The tensile mechanical property test is an important indicator for characterizing the ductility of polymer materials.The paper employs the dissipative particle dynamics simulation method to deeply investigate the effects of chain length and bond energy strength of polymer model molecules on the tensile properties of polymer systems.The simulation studies show that the glass transition temperature of polymer materials is influenced by chain length within a certain range.Increasing chain length and the bond energy of polymer segments can effectively improve the tensile properties of polymer systems.When the chain length is relatively short,the effect of bond energy on tensile properties is limited.The simulation research further analyzes the internal mechanisms by which chain length and bond energy affect polymer materials,providing references for the preparation of strong and tough polymer materials in experiments.关键词
