โœฆ Synopsis

A mathematical model is developed which describes the steady state creep in a welded pipe which is subjected to a constant uniaxial end load and/or uniform internal and external pressure. The model is based on the Cosserat theory of plates and shells and a generalisation of Norton's law. Both asymptotic and analytical solutions are found and the results reveal that bending and thinning of the pipe take place on different length scales.

O'Reilly and Holmes [1] performed experiments and analysis of non-linear motion of a string subjected to vertical oscillation of one end. Their analysis suggested that differences between theoretical and experimental results were mainly due to uncertainty in the assumed form for the forcing function
