| Abstract | ||||
| The creep failure time is calculated for rectilinear thin-walled pipes subjected to combined internal pressure and both of 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. The obtained results were compared with the results obtained by Golub et al. (2004) [2] for pipes under only couple stresses. The present work can be used to calculate the time to creep failure of thin-walled pipes under internal pressure in combination with axial load and binding | ||||
