I am modelling the in-process rolling of a Wire Arc Additive Manufactured (WAAM) wall and need a customised Johnson–Cook constitutive law coded into Abaqus so the simulation captures temperature-dependent plasticity throughout each rolling pass. The physical formulation of the model is already defined; what I lack is the actual implementation—writing, compiling, and integrating the subroutine, setting up the analysis steps, and running the job on a WAAM geometry I will supply. The immediate goals are: • Create and document a UMAT/VUMAT that reflects my modified JC parameters. • Insert it into a fully reproducible Abaqus input deck that simulates simultaneous rolling on the WAAM component. • Provide a concise yet thorough technical report that details assumptions, boundary conditions, mesh strategy, convergence behaviour, and the deformation predictions the model produces. Please attach a brief but specific project proposal outlining how you will tackle the coding, verification, and result extraction stages, along with the turnaround time you need. Only proposals that address those points will be reviewed.
