Image-based characterization data have enabled many important discoveries related to polycrystalline microstructure. New high energy x-ray methods - coupled with detailed structure-based simulations - effectively build on these discoveries by providing real time material response information. The Insitμ center at the Cornell High Energy Synchrotron Source (CHESS) was created to enable researchers to understand the response of polycrystalline structural materials subjected to load. New loading and positioning capabilities enable the creation of grain maps and real-time measurement of lattice strains within each deforming crystal. FEpX, a parallel finite element code developed over the past 20 years at Cornell, is installed on the CHESS compute farm. Users with CHESS projects have access to both experimental and computational resources.
