Recent advances in computational and analytical modeling of the constitutive response of continua, as well as the cost reduction in custom manufacturing of mechatronic/robotic systems, have enabled inverse characterization in an automated fashion. Multidimensional loading paths can be programmed to acquire stimulus-response data sets that encapsulate the behavior of continuum material systems. This allows the application of inverse methodologies for material systems under multifield generalized loading. Such systems can be composite or homogeneous, anisotropic or isotropic material systems that are excitable from more than mechanical loading (i.e., temperature, humidity, electromagnetic fields) such as composite materials for skins of supersonic and hypersonic platforms and their corresponding propulsion applications. Cutting-edge fallout developments in this area involve theories for the multiphysics failure of continua, uncertainty characterization, and propagation from experimental measurements to material constitutive model parameter determination as well as full-field measurement methodologies.
