Web15 Nov 2014 · But now I am moving on tensor damaging models, and I am working on a *UMAT subroutine to model multi axial creep. This is my first experience with UMAT, so I decided to write a Norton law in multi axial form, just to practice with the code. To test the code I rely on some benchmarking example, like axi-symmetric uniaxial specimen, … Web•The three-dimensional stress update algorithms in a co-rotational framework are developed for U–Mo and Zircalloy with the irradiation effects.•An effective method for three-dimensional modeling of the in-pile behaviors in heterogeneously irradiated monolithic fuel plates is established and validated.•The effects of the fission-induced creep effects in the … Websoftware (ABAQUS) through user-subroutine ‘UMAT’. The main deformation mechanisms in the pressure tube under operation are thermal and irradiation creep. Two mechanisms are assumed to independently contribute to the total irradiation deformation.
