3.1 Part deformation during additive manufacturing

Additive manufacturing imposes a severe thermomechanical cycle on material particles, resulting in thermal deformations ε ^th , elastic deformations ε ^e , solid-state phase transformations associated with deformations ε ^tr , plastic deformations ε ^p and creep ε ^v . The evolution of total local deformations can be estimated by adding up the increments of deformation associated with the different mechanisms during the simulation:
