Though hexagonal boron nitride is generally regarded as the most stable boron nitride structure, the relative phase stabilities of boron nitride polymorphs are still under debate. Researchers led by the Japan Advanced Institute of Science and Technology used Monte Carlo simulations to calculate the relative phase stabilities of these polymorphs.

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.
