I am trying to solve elasticity equations by Finite Differnce Method using matlab. i am feeling some problems in applying external loading in form of distributed load. i have discritized the displacemet equation but unable to apply distributed laoded in form of deformation. Can some one help me how to apply stress boundry condition (neumann BC)?

From Boltzmann to Euler: Hilbert's 6th Problem Revisited
Marshall Slemrod
Hi,
I am doing buckling analysis of a pipe with liner inside it. I did eigen buckling on the problem. buckling pressure from my calculation is 15.83Mpa and from ansys it is 15.19Mpa, so I am pretty happy with that. But i would like to do nonlinear buckling analysis on the same problem as a part of my project.
can anyone suggest how to do it using ansys 12,mechanical apdl
Thanks
