okay. I see this now. But I still don't see where is expression comes from (σijδui),j

Hi. I do understand this part. What I'm not understanding is, how to get this expression: (σijδui),j FROM σij,jδui because I earlier asked if the (σijδui),j = σij,jδui where you said no, but as i see from you calculations, then the expression is valid? :) Or?

i didnt get that. Is it possible for you to help me a bit? was the expression valid?: σij,jζui = (σijζui),j

Hi folks. Hope that you can help me. I have an equation, that has been rewritten, and i don't see how: has been rewritten to: Can someone explain me how? Or can someone just tell me if this is correct in tensor notation: σij,jζui = (σijζui),j really hope, that...
