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

Abstract
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.
