| Abstract Scope |
A novel multiaxial miniature testing system (MMTS) with high temperature and in-situ SEM testing capabilities has been developed. Tubular specimen of 1-2 mm diameter with different wall thicknesses can be tested with the MMTS. To obtain bulk material properties from such miniature specimens, it is important to investigate miniature specimen size effect. We report crystal plasticity based multiscale modeling to predict representative volume element and miniature specimen size to obtain bulk material properties from testing with the MMTS. Metallographic analysis was performed on SS304 tubular specimen to obtain grain size and orientation information to develop synthetic microstructure for performing multiscale analyses. Crystal plasticity finite element analysis (CPFEA) was performed to investigate dependence of stress-strain responses on tube wall thickness. This coupling of multiscale modeling and MMTS testing will contribute in rapid development of new material. |
