ABSTRACT: X-rays are well suited for probing materials across multiple length scales, from tomography to diffraction. This talk highlights laboratory scale X-ray scattering approaches we are developing to investigate the micromechanics of materials. We focus on full field stress-strain measurements to extract constitutive behavior and explore the physics of solids, from metamaterials to multimaterial systems. We also pursue quantum entangled X-ray methods that enhance information extraction from low dose measurements. These approaches open new possibilities for studying fragile biological systems and energy materials that were previously inaccessible to conventional X-ray techniques.
