项目摘要

This proposal addresses modelling of the constitutive behaviour of polymers used in construction industry. It includes short-term and long-term performance and failure. Long-term performance influences failure and it is likely the most critical issue that needs to be addressed in order to safely use polymers as structural materials. In this phase of the research, polyethylene (PE) and polyfluoroethylene (based on the comonomers ethylene and tetrafluoroethylene, and usually abbreviated as ETFE) will be studied. Long-term performance and failure (slow crack growth, creep rupture or yield) of PE are directly related to its environmental stress crack resistance (ESCR), which is determined in laboratory conditions. However, the relationship between ESCR and the structural performance of PE in real conditions is not well understood.
该提案涉及建筑业中使用的聚合物的本构行为的建模。它包括短期和长期的业绩和失败。长期性能会影响失效,这可能是为了安全地使用聚合物作为结构材料而需要解决的最关键问题。在这一阶段的研究中,将研究聚乙烯(PE)和聚氟乙烯(基于共聚单体乙烯和四氟乙烯,通常缩写为ETFE)。PE的长期性能和失效(缓慢裂纹扩展、蠕变断裂或屈服)与其耐环境应力开裂性(ESCR)直接相关,后者在实验室条件下测定。然而,在真实的条件下,经济社会责任与体育结构绩效之间的关系还没有得到很好的理解。
