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?
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...
