    Graduate Proving Double Inner Product of Derivative of 2nd Order Tensor w/ Another

    The dot represents material time derivative. A and B are second order tensors, eg Stress. I myself am not clear what \nabla J means here. However, I guess it represents divergence. This was as a homework question for a Continuum Mechanics course. I have not got any luck trying to understand...

    Graduate Proving Double Inner Product of Derivative of 2nd Order Tensor w/ Another

    How do I prove the following: \dot{A}:B + A:\dot{B}=A^{\nabla J}:B+A:B^{\nabla J}

    Graduate Proving Double Inner Product of Derivative of 2nd Order Tensor w/ Another

    Some one please help me how to prove the following: \dot{A}:B + A:\dot{B}=A^{\nabla J}:B+A:B^{\nabla J} A and B are II order tensors and : represents the inner product.
