TY  - JOUR
AB  - This paper presents predictions of the response of sintered FGH96 Ni-based superalloy powder compacts  at  high  temperature,  obtained  by  analysis  of  3D  representative  volume  elements generated by both X-ray tomography and a virtual technique. The response ofthe material to a multiaxial  state  of  stress/strain  for  porosities  as  large  as  0.3  is  explored,  obtaining  the  yield surfaces and their evolution as well as scaling laws for both elastic and plastic properties. The two modelling approaches are found in good agreement. The sensitivity of the predictions to particle  size,  inter-particle  friction,  applied  strain  rate,and  boundary  conditions  is  also examined.
