Thank you Jean-Paul. I did not hear about L2-projection method before, but it seems that the L2-projection method also evaluates the stress tensor at the quadrature points and then finds the cell-averaged stress. The only difference compared with the heuristic method is that it solves AX = Y where A is mass matrix, Y is integration of cell-averaged stress component and X is the nodal stress component that we want. Is that right?
