Thanks to all those who looked at my query below but I now have my answer so no longer require further assistance. Cheers - Gem

Hi,

I am doing an assignment for my final project for my Open University degree. I am doing it on cellulose bionanocomposites. I'm doing ok with the "normal" chemistry but I am struggling with some of the material science. Some of the papers I have researched report upon the "strain-to-failure" of the bionanocomposite films they have produced. I know that strain-to-failure measures the amount of strain a solid material can withstand before it "fails", is calculated from measurements gained from stress-strain curves and is expressed as a percentage. What I don't understand is what the percentage is actually measuring - what is it a percentage of? I have performed google searches and looked through the material science books I have to hand but have received no joy. Please can anyone help me?

Many thanks,
Gemma

I won't answer your question but to give you adivice try looking at civil engineering books because that topic is very relative to the course.they are very concern to that!
