Lame's equation for thick walled cylinder
WebbLame’s theorem gives the solution to thick cylinder problem. The theorem is based on the following assumptions: Material of the cylinder is homogeneous and isotropic. Plane sections of the cylinder perpendicular to the longitudinal axis … WebbB. Thick-walled Cylinder Subjected to External Pressure We consider the thick-walled cylinder with the same properties used in previous internal pressure case. Then the initial approximation for the solution according to Eq.(29) becomes the same as in previous case as follows: 0 [ ] 10 3 ( ) (0.3) (1.2) (0.3) 9 r ur u u u − =+ − (38)
