| Abstract: | A new method is proposed to calculate the critical fl ow velocity of pipes conveying fluid. The problem of buckling is transformed into the matrix eigen-problem using a method combining singularity functions with F ourier series. This method can be used for pipes with variant elastic supports o n ends and/or in a middle position. |
