3. The explosion of a solid explosive material in the form of an infinite cylinder may be described by d du -14 (d) = = 2e", 0<r< 1, with BC: (0) = 0,u(1) = 0 r dr The exact solution of this nonlinear equation is: u(r) = ln; (1+r²)² Find the FEM solution using two linear elements and compare with the exact solution.
