| Abstract | ||||
| The creep failure time is calculated for rectilinear thim-walled pipes subjected to torsion as well as tension and bending. The calculating of the failure time is given using the concept of equivalents stresses. The equivalent stresses are found from the mixed delayed-failure criterion relating the maximum normal stress and the intensity of tangent stresses. Results for failure time which are made of steel alloys are presented and compared with the results obtained by Golub et al. (2004) [3]. The present work can be used to calculate the time to creep failure for any thin-walled pipes under torsion, axial load and bending. | ||||
