英文摘要
This proposal addresses modelling of failure of polyethylene (PE) in the context of the applicability of this material for the construction industry. Long term performance of PE is likely the most critical issue that needs to be addressed in order to safely use PE and similar polymers as construction materials. 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 polyethylene in real conditions is not well understood.
