So what you are trying to say is that creep doesn't necessarily cause the microcrack propagation because the plastic is being relieved by its natural occurrence to recover?
Is that why once when the plastic has turned opaque, it doesn't totally recover to become translucent as it once was? Once...
Wow, thanks for the detailed response.
I was still wondering whether it could be that polypropylene also has this kind of reaction during creeping? I also know that when the load has been taken away from the material there will be recovery...
So does that mean the chains are starting to...
Thanks for the reply!
Anyway i read up regarding Stress Whitening, sources say that the plastic crystallites were broken into smaller pieces in the stress-whitened material than in the translucent areas.
So plastic starts turning white when its molecular bond is being broken? Such as...
I was doing a project to test for creep in materials, and one of the things that I wonder would be the fact that the translucent plastic would start to turn opaque when it starts to strain, just like why plastics when bent starts to turn white where the bend is. Why is this so? I know creep is...
