Modeling the mechanical behavior of fiber-reinforced polymer composites is difficult because of their nonlinear response to external stimuli. Constitutive relations offer one way to account for the nonlinearity, and a team of researchers in Russia used this approach to model polymer composites designed as shut-off valves for pressure vessel service equipment.

To describe electronic charge transport in oxides, researchers rely on a small-polaron transport model that was developed six decades ago for binary oxides rather than higher-order systems. Researchers from Cornell University and Technion–Israel Institute of Technology have now updated the model with additional parameters to more accurately model complex oxide systems.
