Dear All,
Not sure I'm posting in the correct subforum here, but I'm wondering if anyone can help me understand how to expand the following: δu_{i,j}(δ_{im}+u_{i,m}) I can't quite get to grips with the indicial notation in the example, the δu_{i,j} is the variation of u (displacement in this example) and the δ_{im} is the kronecker delta.. I just want to expand the brackets, can anyone offer any advice on how to do this. Many thanks
