Abstract
This paper shows an analytical and numerical consideration of dominant normal stresses in the pipe wall. Several causes for the stress are considered, the bending, the internal pressure of a long pipe, the pipe's own weight and the external surface load due to the soil pressure. The solution is obtained analytically if possible and compared with the numerical solution obtained using own programing based on the finite volume method (FVM). The test case for the numerical method and the developed computer program is analyzed via available set of analytical solutions in theory of elasticity and then the numerical method is applied on the test case in order to compare the results and verify and validate the FVM algorithm. Some results are checked using theĀ finite element method in Matlab.
