Modelling the creep in a welded plate using a three-director Cosserat model

Craine, R.E. and Newman, M.G. (1996) Modelling the creep in a welded plate using a three-director Cosserat model Acta Mechanica, 117, (1-4), pp. 11-21. (doi:10.1007/BF01181033).

Record type: Article


Cracking in ferritic weldments at high temperatures often occurs outside the weld in the narrow type IV region (which is sometimes called the low-temperature heat affected zone). In this paper a mathematical model is developed for the steady-state creep of a flat plate of constant thickness, under uniaxial end loading. The model is based on the Cosserat theory of plates and a multi-axial version of Norton's law and includes three directors. Results for the steady-state creep strain-rate are calculated for values of the material parameters based on a ferritic material which is susceptible to cracking in the type IV region.
