Interior structure research focuses on the study of the internal composition, organization, and dynamics of objects, structures, or systems. This can include anything from the internal structure of materials, such as metals or crystals, to the internal structure of planets or stars. Researchers in this field use a variety of techniques, such as imaging, modeling, and simulations, to explore and understand the properties and behaviors of different internal structures. By studying interior structure, researchers can gain insights into the formation, evolution, and function of various objects, as well as develop new materials or technologies based on these findings.
