Terms within in the integral how to simplify in case of 2d and axisymmetric caseformulation of cst, quad and axisymmetric problems. how the terms within integral is taken.? how the potential energy is formulated for CST,QUAD and Asisymmetric problems. I am much interested in formulation part. How the formulation of strain energy, body force and traction force is done. I mean how the potential energy pi is simplified. once after simplification of pi i can do the derivation part like obtaining stiffness matrix and getting work potential.For CST and axisymmetric problems how the traction force is taken in to consideration.For axisymmetric problems how the strain energy is formulated.SIMPLIFIED PI FOR CST AND AXISYMMETRIC PROBLEMS IS MY INTEREST
