It depends on what type of polymer you're trying to simulate. For brittle polymers, LEFM should be able to work. While for many ductile polymers, elastic-plastic fracture mechanics should be used.
PE has significant plasticity compared with most metals. Basically, fracture is impossible when plasticity is too huge, only necking occurs. What is the service condition of your LLDPE?

Can you please berif on what are the major changes from fracture in metals
