Hi, I am trying to develop an equilibrium equation using the principle of virtual work & have a long expression for the internal & external virtual work. I now need to perform integration by parts on the generalized coordinates in 2-D (Green's theorem) to get my equilibrium equation & the boundary conditions.
I would be very thankful if someone can kindly guide me as to how I can perform integration by parts symbolically to transfer the differentiation & get the associated boundary conditions.
I want to learn how to do integration by parts in Mathematica.
I know how to to solve this problem in mathematics.
